Use the variable u for the inside function to express each for the following as a composite function

a)y=(8t^2-1)^3

u(t)= ?

y(u) =?

Note: u(t) is the inside function and y(u) is the outside function

b) P=11e^-0.1t

u(t)= ?

P(u) =?

Note: u(t) is the inside function and P(u) is the outside function

c) C=5 ln(q^6 + 6)

u(q)= ?

C(u) =?

Note: u(q) is the inside function and C(u) is the outside function
