Question

Function problem

Answer 1

\(\bf f(x)=49-x^2\qquad g(x)=7-x\qquad (f-g)(x)\implies f(x)-g(x)
\\ \quad \\

f(x)-g(x)\implies (49-x^2)-(7-x)\)

Answer 2

yes, don't forget to distribute the "-" negative, in front of the parentheses

Answer 3

hmmm did you distribute the negative?

Answer 4

ok... so... let us distribute it -(7-x) = ?

Answer 5

or I should say
-(7-x) => -1 * (7-x) => ?

Answer 6

yeap thus
\(\bf f(x)=49-x^2\qquad g(x)=7-x\qquad (f-g)(x)\implies f(x)-g(x)
\\ \quad \\

f(x)-g(x)\implies (49-x^2)-(7-x)\implies (49-x^2)-7+x
\\ \quad \\
49-x^2-7+x\implies -x^2+x+42\)

Answer 7

Oh, I see. Thanks so much!
