Question

dada a funcão (f)=2×+5 determine o valor dada. a)f(5),f(-2),f(0)​

Answer 1

Resposta:

f(x) = 2x + 5

a)

f(5) = 2*5 + 5 = 10 + 5 = 15

b)

f(-2) = 2*(-2) + 5 = -4 + 5 = 1

c)

f(0) = 2*0 + 5 = 5

Answer 2

Resposta:

f(x)=2x+5

f(5)=2×5+5=

10+5

15

f(-2)=2×(-2)+5

-4+5

1

f(0)=2×0+5

0+5

5
