For each function, find f (-1), f (0), and f (2).

f (x) = 4x-3

f (x) = 1/2x+2

f (x) = 4x-3

f (-1) = 4 (-1) - 3=-4-3 = - 7

f (0) = 4 (0) - 3 = - 3

f (2) = 4 (2) - 3=8-3 = 5

f (x) = 1/2x+2

f (-1) = 1/2 (-1) + 2=1 / (0) = unknown

f (0) = 1/2x+2=1/2 (0) + 2=1/2

f (2) = 1/2x+2 = 1/2 (2) + 2=1/6
