Answer: -3
Explanation:
Same thing as last time.
f(x) just means y. The y-axis is the verticle one, and the x-axis is the horizontal one.
We are looking for the x coordinate because f(?) = -3 just means that
f(x) = -3
which means
y = -3
so we look at -3 on the y-axis and find our x coordinate, which just so happens to be -3 as well.
