Question

Find g(f(x))

Answer 1

Is there a g= and a f=?

Answer 2

If f(x) \[\sqrt{x-3}\] and g(x) = \[\sqrt{{x ^{2}}+5}\]

Answer 3

f(x) = sqrt(x-3)
To find g(f(x)), replace all the xs in g(x) by sqrt(x-3)
g(f(x))

Answer 4

g(f(x)) = sqrt[ (f(x))^2 + 5 ]
just replace that f(x) by sqrt(x-3)

Answer 5

and then simplify.

Answer 6

Yep that's what I did, and I got sqrt(sqrt(x^2 + 5) - 3)

Answer 7

no u found f(g(x)), do it the other way around.

Answer 8

u plugged in g(x) into f(x). U gotta plug in f(x) into g(x)

Answer 9

Ah ok. Cheers
