Transforming equation

What is transformation equation?

Transformation of equations 1 – definition 1. Transformation of an equation into another equation whose roots are. reciprocals of the roots of a given equation we replace x→x1. 2. Transformation of an equation into another equation whose roots are negative of the roots of a given equation we replace x→−x.

What is the equation of the transformed function?


y = f(x) + C C > 0 moves it up C < 0 moves it down
y = f(x + C) C > 0 moves it left C < 0 moves it right
y = Cf(x) C > 1 stretches it in the y-direction 0 < C < 1 compresses it
y = f(Cx) C > 1 compresses it in the x-direction 0 < C < 1 stretches it
y = −f(x) Reflects it about x-axis

How do you describe transformations?

A function transformation takes whatever is the basic function f (x) and then “transforms” it (or “translates” it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around. This is three units higher than the basic quadratic, f (x) = x2. That is, x2 + 3 is f (x) + 3.

What are the 4 types of transformations?

There are four main types of transformations: translation, rotation, reflection and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

What are reflections in math?

A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.

What are the 7 parent functions?

The following figures show the graphs of parent functions: linear, quadratic, cubic, absolute, reciprocal, exponential, logarithmic, square root, sine, cosine, tangent.

What is the rule for transformation?

The function translation / transformation rules: f (x) + b shifts the function b units upward. f (x) – b shifts the function b units downward. f (x + b) shifts the function b units to the left.

How do you stretch a function?

To stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ).

How do you shift a function horizontally?

The function h(x) = f(x + a) represents a horizontal shift a units to the left. Informally: Adding a positive number after the x inside the parentheses shifts the graph left, adding a negative (or subtracting) shifts the graph right.

How do you vertically stretch a function?

Key TakeawaysWhen by either f(x) or x is multiplied by a number, functions can “stretch” or “shrink” vertically or horizontally, respectively, when graphed.In general, a vertical stretch is given by the equation y=bf(x) y = b f ( x ) . In general, a horizontal stretch is given by the equation y=f(cx) y = f ( c x ) .

What order do you transform functions?

Apply the transformations in this order:Start with parentheses (look for possible horizontal shift) (This could be a vertical shift if the power of x is not 1.)Deal with multiplication (stretch or compression)Deal with negation (reflection)Deal with addition/subtraction (vertical shift)

How do you describe transformation reflection?

A reflection is a type of transformation. It ‘maps’ one shape onto another. When a shape is reflected a mirror image is created. If the shape and size remain unchanged, the two images are congruent.

What are the most common types of transformations?

Translation is when we slide a figure in any direction. Reflection is when we flip a figure over a line. Rotation is when we rotate a figure a certain degree around a point.

Equation of vertical line

How do you write an equation for a vertical and horizontal line? Horizontal lines go left and right and are in the form of y = b where b represents the y intercept. Vertical lines go up and down and are in the form of x = a where a represents the shared x coordinate […]

Bernoulli’s equation example

What does Bernoulli’s equation State? Bernoulli’s principle states the following, Bernoulli’s principle: Within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed. Why is Bernoulli’s equation used? The Bernoulli equation is an important expression relating pressure, height and velocity of a fluid at one […]
