Question

what is the composite function (SoP)(y) where S(x)=x^2 & P(x)=2^x the answer should be in number

Answer 1

my answer comes 2^2x :(

Answer 2

sorry 2^2y

Answer 3

2^2y is correct.

Answer 4

then why in text this condition is mentioned "In each case your answer should be a number"?

Answer 5

similarly for S(x)=x^2 and s(x)=sinx then (Sos)(y)=sin^2 y

Answer 6

this is not a number but the answer is written in form of sin^2 y in the solution mannual

Answer 7

Maybe you can learn something more about y?

Answer 8

y is not given

Answer 9

it's in Spivak

Answer 10

What's Spivak?

Answer 11

Spivak's calculus book which is more of analysis

Answer 12
