F(x) = 4 - X
What is f(-3)?
show work

7

Step-by-step explanation:

By using the formula you just need to place -3 where X is being that X will represent F. After placing -3 where it needs to be it should look like this:

4-(-3)

Remove the parathesis and whenever there is a - in front of - in a parathesis you need to change the sign:

4+3

Add the numbers and you get:

7

your answer is 228

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
