Given r(x) = x square +2x -1 and s(x) = x-1 what is the value of r(s(3))

Step-by-step explanation:

we have

we know that

The function composition is equal to

(r ∘ s )(x) = r(s(x))

In the function r(x) substitute the variable x by the function s(x)

so

For x=3

substitute the value of x=3 in the function composition
