Question

Para f(x) = 3x - 8, calcule
a)f(0) =
b)f(-2)
c)f(x)=1/2

Answer 1

Explicação passo-a-passo:

a)

f(x) = 3x - 8

f(0) = 3.0 - 8

f(0) = 0 - 8

f(0) = -8

b)

f(x) = 3x - 8

f(-2) = 3.(-2) - 8

f(-2) = -6 - 8

f(-2) = -14

c)

f(x) = 3x - 8

3x - 8 = 1/2

2.3x - 2.8 = 1

6x - 16 = 1

6x = 1 + 16

6x = 17

x = 17/6
