Question

Dada a função f (x) = 8x + 15, calcule:
a) f(0)

b) f(5)

c) f(2)

d) f(3)

Answer 1

f(0) = 8 . 0 + 15

0 + 15

15

f(5) = 8 . 5 + 15

40 + 15

55

f(2) = 8 . 2 + 15

16 + 15

31

f(3) = 8 . 3 + 15

24 + 15

39

Answer 2

Explicação passo-a-passo:

f(x) = 8x + 15

a)f(0)

f(0) = 8.0+15

f(0) = 15

b)f(5)

f(5) = 8.5+15

f(5) = 55

c)f(2)

f(2) = 8.2+15

f(2) = 31

d)f(3)

f(3) = 8.3+15

f(3) = 39
