Question

Calcule os valores indicados na função:

a. f(x) = 3x + 5; f(0), f(-1), f(2)

Answer 1

f(0)= 3.0+5=5

f(-1)= 3.(-1)+5=-2

f(2)= 3.2+5=11

Answer 2

f(x) = 3x + 5

f(0) = 3 • 0 + 5

f(0) = 0 + 5

f(0) = 5

f(-1)= 3 • ( - 1) + 5

f(-1) = - 3 + 5

f(-1) = 2

f(2)= 3 • 2 + 5

f(2) = 6 + 5

f(2)= 11
