Question

1) Dada a função f(x)=-3x + 2, calcule:
a) f(-2)
b) f(2/3).
c) f(0)​

Answer 1

Explicação passo-a-passo:

f(x) = -3x + 2

a) f(-2) = [-3 × (-2)] + 2

f(-2) = 6 + 2

f(-2) = 8

b) f(2/3) = (-3 × 2/3) + 2

f(2/3) = -6/3 + 2

f(2/3) = -2 + 2

f(2/3) = 0

c) f(0) = (-3 × 0) + 2

f(0) = 0 + 2

f(0) = 2
