How do you know if a function is even or odd?
You may be asked to “determine algebraically” whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Different Types Of Math Transformation
There are different types of math transformation, one of which is the type y = f (bx). This type of math transformation is a horizontal compression when b is greater than one. We can graph this math transformation by using tables to transform the original elementary function.
How do you tell if a graph is horizontally stretched or compressed?

How do you vertically stretch a quadratic equation?
If A > 1, the function is stretched vertically. If A < 1 it is compressed vertically, and if A is negative, it still scales the graph by |A|, but it is also flipped across the x-axis. For example, f (x) = x2 has a vertex of (0, 0) and opens upward, but g (x) = -x2 opens downward – but has the same vertex.
How do you find the horizontal shift?
the horizontal shift is obtained by determining the change being made to the x-value. The horizontal shift is C. The easiest way to determine horizontal shift is to determine by how many units the “starting point” (0,0) of a standard sine curve, y = sin (x), has moved to the right or left.
Is a vertical stretch a dilation?
A dilation is an enlargement (or reduction) that is “uniformly” applied to a figure. The image of a dilation is the same shape as the original figure, but is not necessarily the same size. Both the vertical length and horizontal length of a dilated figure are increased (or decreased) by the same factor.

Vertical shifts are outside changes that affect the output ( y- ) axis values and shift the function up or down. Horizontal shifts are inside changes that affect the input ( x- ) axis values and shift the function left or right.
How do you do a vertical stretch by a factor of 3?

What does a vertical shift look like?
We can express the application of vertical shifts this way: Formally: For any function f (x), the function g (x) = f (x) + c has a graph that is the same as f (x), shifted c units vertically. If c is positive, the graph is shifted up. If c is negative, the graph is shifted down.
Why is there a vertical stretch by a factor of 1/2?
There is a vertical stretch by a factor of 1/2, and a horizontal stretch by a factor of 1/2 because you would have to multiply all previous input values by 1/2 to get the same output as f (x).
What is scale factor?
Based on what you've said, you are always using "scale factor" to mean a multiplier; so in your class's usage, you can't say " compression by a factor of 3 ", though others do. You would say compression by a factor of 1/3 (that is, multiplying by 1/3).
Why is it dangerous to get information online?
