Question

Now, to combine the functions, substitute x(y) = z from Part B and simplify the function f(z) = 6z + 5 that you wrote in part C.

Answer 1

The simplified function of f(z) = 6z + 5 is f(y) = 6y + 5

How to simplify the functions?

The functions are given as:

x(y) = z

f(z) = 6z + 5

Next, we substitute x(y) = z in the equation f(z) = 6z + 5

So, we have:

f(y) = 6y + 5

Hence, the simplified function of f(z) = 6z + 5 is f(y) = 6y + 5
