Question

Given the function rule f(x)=^2-4x+3, which is the output of f(-3)?

Answer 1

24

Explanation:

Where are the given answer choices? Please note that ^2 cannot stand alone; you meant x^2.

If f(x)=x^2-4x+3, f(-3) is found by subbing -3 for x in f(x)=x^2-4x+3:

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

= 9 + 12 + 3

= 24
