Question

Encontre o valor numérico da função f(x) = 3 x – 4 sendo :
a) F(-6)
B) F(2/3)
c) F(4)
d) F(-5/2)

Answer 1

f(x) = 3 x – 4

a) F(-6)

f(-6) = 3(-6) – 4

f(-6) = -22

B) F(2/3)

f(2/3) = 3(2/3) – 4

f(2/3) = -2

c) F(4)

f(4) = 3(4) – 4

f(4) = 8

d) F(-5/2)

f(-5/2) = 3(-5/2) - 4

f(-5/2) = -11,5
