Question

this is evaluating quadratic functions ?

if a(x)=3x+6 and c(x)=x^2-7x+8
and the problem is a(x)-c(x) how do I solve it?

Answer 1

subtract both functions

Answer 2

\[\huge\rm \color{Red}{a(x)} -\color{blue}{ c(x)}\]
a(x) =3x+6
so replace a(x) with 3x+6 \[\huge\rm \color{reD}{3x+6}-\color{blue}{(x^2-7x+8)}\]
