QuestionFind $(k \circ m)(x)$ and $(m \circ k)(x)$ for $k(x)=9x-5$ and $m(x)=x^2$. Are they equal?

Studdy Solution
Finally, we compare $(k \circ m)(x)$ and $(m \circ k)(x)$ to see if they are equal.
$$9x^{2} -5 \neq81x^{2} -90x +25$$So, $(k \circ m)(x) \neq (m \circ k)(x)$.
The solutions are(a) $(k \circ m)(x) =9x^{2} -5$ (b) $(m \circ k)(x) =81x^{2} -90x +25$ (c) $(k \circ m)(x) \neq (m \circ k)(x)$
