Question

Assume f(x) = -2x+8 and g(x) = 5x. What is the value of (f o g)(3)?

Answer 1

A.17
B. 3x + 8
C. -22
D. 29

Answer 2

\(\bf (fog)(x) \implies f(g(x))\\
\textit{say if g(3) is } \square\\
f(g(x)) \implies f(\square)\)

Answer 3

I am sorry there are characters i can not see.

Answer 4

you mean \(\bf \square ? \)?

Answer 5

it's just a blank :), so it's meant to be so

Answer 6

Oh I see, I am just having a hard time understanding this stuff!

Answer 7

we know that f(x) = -2x+8 and g(x) = 5x

so (fog)(3) => f( g( 3 ) )

so whatever g( 3 ) is
"f" function will use THAT

Answer 8

so, what's g(3)?
