Question

B) f(x) =4x-2
f (0) =
f(1) =
f(2)=
f(-1)
f(-2)​

Answer 1

Na função, basta trocar X pelo número que temos:

f(x) = 4 × x – 2

↓ ↓

f(0) = 4 × 0 – 2

f(0) = $\Large\boxed{-2}$

f(1) = 4 × 1 – 2

f(1) = $\Large\boxed{2}$

f(2) = 4 × 2 – 2

f(2) = $\Large\boxed{6}$

f(-1) = 4 × (-1) – 2

f(-1) = $\Large\boxed{-6}$

f(-2) = 4 × (-2) – 2

f(-2) = $\Large\boxed{-10}$
