Question

dada a função f(x) =5x+3,determine:
a)f(-2)

b)f(5)

c)f(0)

d) (-8)​

Answer 1

f(x) = 5x +3

a)f(-2) = 5(-2) +3 = -10 +3 = -7

b)f(5) = 5(5) +3 = 25 +3 = 28

c)f(0) = 5(0) +3 = 0 +3 = 3

d) (-8) = 5(-8)+3 = -40+3 = -37

Answer 2

f(x) = 5x + 3

a) f(-2) = 5.(-2) + 3 = -10 + 3 = -7

b) f(5) = 5.5 + 3 = 25 + 3 = 28

c) f(0) = 5.0 + 3 = 0 + 3 = 3

d) f(-8) = 5.(-8) + 3 = -40 + 3 = -37
