Question

What is the value of f[g(5)] for the functions f(x) = 2x + 1 and g(x) = 2x - 5 ? Please I don't get it at all.

Answer 1

whats g(5)?

Answer 2

so first solve function g(x) with x = 5 then whatever you get from that, substitute into f(x) and solve that

Answer 3

I have no idea, im taking a test and thats the problem they gave me

Answer 4

uh...

Answer 5

g(5)=2(5)-5=10-5=5

Answer 6

so five is the answer?

Answer 7

no 5 is g(5):)
now f(g(5))=f(5)=2(5)+1=11 which is the answer

Answer 8

OHHH i see how you did it, thanks!

Answer 9

good

Answer 10

"im taking a test" is always rife with bad vibes ...
