Answer: 29
==========================================================
Step-by-step explanation:
We replace every copy of x with -2. From there, use PEMDAS to simplify
y = 3x^2 + 17
y = 3(-2)^2 + 17
y = 3(4) + 17
y = 12 + 17
y = 29
Therefore, x = -2 pairs up with y = 29.
Put another way, the point (x,y) = (-2, 29) is on the function curve.
