Given the function rule f(x) = x² – 3x + 2, what is the output of f(–2)?
a.)–8
b.)0
c.) 4
d.)12

D

Step-by-step explanation:

1) Plug in -2 for x

(-2)^2-3(-2)+2

2) Simplify

4+6+2

12

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
