Question

Dada a função definida F(x)=5x-3 calcule f(7) ,f(-2) e f(3)

Answer 1

Explicação passo-a-passo:

f(x) = 5x - 3

a) f(7) = 5.7 - 3

f(7) = 35 - 3

f(7) = 32

b) f(-2) = 5(-2) - 3

f(-2) = -10 - 3

f(-2) = -13

c) f(3) = 5.3 - 3

f(3) = 15 - 3

f(3) = 12

Answer 2

$f(x)=5x-3\\ \\ f(7)~~==>f(7)=5(7)-3=32\\ \\ f(-2)~~==>f(-2)=5(-2)-3=-13\\\\f(3)~==>f(3)=5(3)-3=12$
