Question

Da função f(x)=8x-1, determine
a) f(5)
b) f(-1)
c) f(0)
d)f(¼)
​

Answer 1

Resposta:

a) f(5)=8x-1

f(5)=8.5-1

f(5)=40-1

f(5)=39

b) f(-1)=8x-1

f(-1)=8.(-1)-1

f(-1)=-8-1

f(-1)= -9

c) f(0)=8x-1

f(0)=8.0-1

f(0)=0-1

f(0)= -1

d)f(¼)=8x-1

f(0)=8.1/4 -1

f(0)=8/4-1

f(0)=2-1

f(0)=1
