Question

Diketahui fungsi f dengan rumus fungsi f(x) = 4x-2. Tentukan nilai
a. F (2)
b. F (-3)
c. F (-2) f(3)

Answer 1

F(2) = 4(2) - 2
> 8 - 2 = 6

f(-3) = 4(-3) - 2
>-12 - 2 = -14

f(-2) = 4(-2) - 2
>-8 - 2 = -10
f(3) = 4(3) - 2
>12 - 2 = 10
=>f(2) f(3)
>-10 x 10 = -100

Answer 2

A. f(2)
= 4 . 2 - 2
= 8 -2
=6

b. f(-3)
= 4 . (-3) -2
= -12 -2
= -14

c. f(-2)
= 4 . (-2) -2
= -8 -2
= -10
f(3)
= 4 . 3 -2
= 12 - 2
= 10
f(-2) . f(3) = -10 . 10
= -100
