Question

Dada a função f(x)=2x-1 e g(x)=3x+5.Determine


G(10)-G(5)-G(2)
F(10)-F(s)-F(2)

Answer 1

Resposta:

g(x)=3x+5

g(10)=3*10+5=35

g(5)=3*5+5=20

g(2)=3*2+5=11

g(10)-g(5)-g(2)=35-20-11=4

f(x)=2x-1

f(10)=2*10-1=19

f(s)=2*s-1=2s-1

f (2)=2*2-1=3

f(10)-f(s)-f(2)= 19-(2s-1)-3

=19-2s+1-3

=-2s+17
