Use f(x)=-2x+5 to find x when f(x)=11

1 answer:

3 0

When it asks this question, ultimately you want to plug 11 into x because its f(x). 11=-2+5.

Then you subtract 5 on both sides because of the opposite of addition is subtraction.

6=-2x

now divide on both sides

x=-3

Linear Transformations<br><br> To reflect a linear function about the y-axis, the slope is what

baherus [9]

Answer: Multiplied by -1

Example:

Let's say we had the linear function y = 2x+5

Reflecting this over the y axis means we replace every x with -x and simplify

y = 2x+5 becomes y = 2(-x)+5 and that simplifies to y = -2x+5

The y intercept stays the same the whole time. This is because the y intercept is on the mirror line of the y axis. Stuff on the mirror line does not move.

Notice the jump from the old slope (2) to the new slope (-2) has us multiply by -1.
