Question

1 - Considere a função f(x)=6,50x, resolva:
a) f(9) =
b) f(1) =
c) f( ) = 13,00
d) f( ) =19,50
e) f(20)​

Answer 1

Explicação passo-a-passo:

a)

f(9) = 6,50.9

f(9) = 58,50

b)

f(1) = 6,50.1

f(1) = 6,50

c)

6,50x = 13,00

x = 13,00/6,50

x = 2

d)

6,50x = 19,50

x = 19,50/6,50

x = 3

e)

f(20) = 6,50.20

f(20) = 130
