Question

= Homework: Module 17If r(x) =find r(a) and write the answer as one fraction.X-29r(a) =(Simplify your answer. Do not factor.)

Answer 1

As given by the question

There are given that function

`r(x)=(7)/(x-2)`

Now,

To find the value of r(a^2), put x = a^2 into the function

Then,

`\begin{gathered} r(x)=(7)/(x-2) \\ r(a^2)=(7)/(a^2-2) \end{gathered}`

Hence, the function is shown below:

`r(a^2)=(7)/(a^2-2)`
