Question

Consider the functions f(x) = 2x + 1 and g(x) = x2 − 10. What is the value of (f + g)(−2)?

a.−9
b.−6
c.−3
d.9

Answer 1

I already told you what to do.

Answer 2

is that f of (g of x)?

Answer 3

there for it would be 9

Answer 4

never knew you can add up functions like that.

Answer 5

NO, f of g(x) is written as \[(f ○ g)(x)=[f \left( g \left( x \right) \right)\]
\[\left( f+g \right)(x)=f(x)+g(x)\]

Answer 6

Oh.
