Question

Use the function to answer the question.
f(x) = 7-x if x <= -2
4x^2 if -20 What is the value of f(-3)?

Answer 1

so x = -3 means that you need to use the first one, look at the conditions.

it says if x is less than -2 which -3 is then use this choice

f(x) = 7 - x

now just substitute x = -3 for the answer

if x is between -2 and 0 then use the middle choice... etc.

hope it helps
