Question

52. Se f(x) = 5x + 1 e h(x) = 1 + 4x, calcule:
f(h(2)) + h(f(2)).

Answer 1

52. Se f(x) = 5x + 1 e h(x) = 1 + 4x, calcule:

h(2)=1+4.(2)

h(2)=1+8

h(2)=9

____

f(2)=5.(2)+1

f(2)=10+1

f(2)=11

__

f(h(2)) + h(f(2))=f(9)+h(11)

f(h(2)) + h(f(2))=5.(2)+1+1+4.(11)

f(h(2)) + h(f(2))=10+1+1+44

f(h(2)) + h(f(2))=11+45

f(h(2)) + h(f(2))=56
