Question

1. Dada à função do 1º. Grau F(x) = (1-5x). Determine
(a) 0;
(b) 1;
(c) 2;
(d) 4;
(e) 5.​

Answer 1

f(x) = 1 - 5x

A) f(0) = 1- 5(0)

    f(0) = 1

B) f(1) = 1 - 5(1)

    f(1) = 1 - 5

    f(1) = -4

C) f(2) = 1 - 5(2)

    f(2) = 1 - 10

    f(2) = -9

D) f(4) = 1 - 5(4)

    f(4) = 1 - 20

    f(4) = -19

E) f(5) = 1 - 5(5)

   f(5) = 1 - 25

   f(5) = -24
