Question

If f(x) = x2 + 1, what is the ordered pair for x =
-4.?

Answer 1

D). (-4, 17)

Explanation:

Plug in -4 for x.

`f(-4)=(-4)^2}+1`

Solve.

`f(-4)=16+1`

`f(-4)=17`

We already know that the x-coordinate is -4. (-4, y)

f(x) stands for y, so y=17.

(-4, 17)

I hope this helps!

Answer 2

(-4,17)

Explanation:

y = f(x)

f(-4) = (-4)^2+1 = 17

y-coordinate = 17
