q(x)= x^2 + 3 r(x)= radical sign (x +2)

Question

(r • q)(2) =

(q • r)(2) =

It’s finding the composition of two functions.

Answer 1

(r • q)(2)

First evaluate q(2) = (2)²+3 = 7

Then plug this value into r(7) = √(7+2) = √9 = 3

(q • r)(2)

First evaluate r(2) = √(2+2) = √4 = 2

Then plug this value into q(2) = (2)²+3 = 7
