Find the following values if:

f(x) = 3x - 2 and g(x) = 4x2 + 5

c) f(-1) =

d) g(-3) =

e) f(5) - g(2) =

1. c)

f ( - 1 ) = 3 ∙ ( - 1 ) - 2 = - 3 - 2 = - 5

d)

g ( - 3 ) = 4 ∙ ( - 3 )² + 5 = 4 ∙ 9 + 5 = 36 + 5 = 41

e)

f ( 5 ) - g ( 2 ) = 3 ∙ ( 5 ) - 2 - [ 4 ∙ ( 2 )² + 5 ] =

15 - 2 - ( 4 ∙ 4 + 5 ) = 13 - ( 16 + 5 ) = 13 - 21 = - 8
