given the function rule f(x)=x^2-3x+2, what is the output of f(-2)?

A: -8
B: 0
C: 4
D: 12

f(-2)=(-2)^2-3(-2)+2=4+6+2=12

The answer is D: 12.

To find the output of the function f(x) = x^2 - 3x + 2 when x = -2, we substitute -2 into the function.

f(-2) = (-2)^2 - 3(-2) + 2
= 4 + 6 + 2
= 12

Therefore, the output of f(-2) is 12.

The correct answer is D: 12.
