Just want to check and see if I'm on the right track,

1. Evalyate F(-3) = 4x^2 - 3x - 5,
F(-3) = 4(9) - (9) - 5
F(-3) = 36 - 4 = F(-3) = 32

2. The value of a computer after t years is given by the depreciation function V(t) = $2000 - 150t. Waht is the value of the computer 4 years after it is purchased? V(t) =$2000 - 150t =
V(4) = $2000-$600=

Re: Functions

Hi, this is the exact wording for this problem it just asks me to write a linear function for this problem, and it only gives me two prices. In the next qustion is asks about a customer traveling more miles.
