Question

I am having issues with this problem I don't seem to understand the product of functions :( If someone could explain it please
f ( x ) = 2x + 3
g( x ) = 4x − 5

a. Using these functions compute each of the following.

• f (g ( x ))
• g (f ( x ))

Answer 1

thats not the product of functions, thats called the composition of functions

Answer 2

f o g (x) = f(g(x)) = f (4x - 5) = 2(4x-5) + 3

Answer 3

Appreciate it jayzdd makes sense now!

Answer 4

your welcome :)

Answer 5

can you find g(f(x)) now?

Answer 6

Yeah believe so :D

Answer 7

g(2x+3)=4(2x+3)-5 Like this?
