## What happens when you multiply a function by 2?

We can also stretch and shrink the graph of 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 multiply two equations together?

Steps to Using Multiplying to Solve Linear Systems:

1. Put both equations into standard form (Ax+By=C).
2. Multiply one or both of the equations by a number so that you will have opposite coefficients on the same variable.
3. Add the two equations together.
4. Solve for the variable.

#### How do you multiply a function?

To multiply a function by another function, multiply their outputs. For example, if f (x) = 2x and g(x) = x + 1, then fg(3) = f (3)×g(3) = 6×4 = 24. fg(x) = 2x(x + 1) = 2×2 + x.

Is 2x times 2x 4x squared?

2x times 2x is 4×2 . In an expression such as 2x, 2 is called the coefficient and x is the variable.

What are the multiplications of 4?

## What are stretches in math?

A stretch or compression is a function transformation that makes a graph narrower or wider. stretching. Stretching a graph means to make the graph narrower or wider. Transformations. Transformations are used to change the graph of a parent function into the graph of a more complex function.

### What is Y F 2x?

y=f(2x) The 2 is multiplied rather than added, so it is a scaling instead of a shifting. The 2 is grouped with the x, so it is a horizontal scaling.

#### Can I multiply equations?

The Multiplication Property for Equations states that an equation can be multiplied or divided by the same number on each side of the equation without changing the solution to the equation. Solution: Isolate the w by dividing each side of the equation by 13. Multiply the fractions on the left side of the equation.

Which math function is used to multiply itself 4 times Java?

pow() is an built-in method in Java Math class and is used to calculate the power of a given number. The power of a number refers to how many times to multiply the number with itself.

Does 2x squared equal 4x?

2x squared, denoted (2x)2, is equal to 4×2.
