Question

f(x) = Sqrt x + seven.; g(x) = 8x - 11

Find f(g(x)) , I keep getting it wrong ;(

Answer 1

I thought it was \[\sqrt{8x-11+7}\]

Answer 2

yes it is right :)
but simplify it more "-11+7"

Answer 3

\[\sqrt{8x-4}\]

Answer 4

but it says the right answer is \[\sqrt[2]{2x-1}\], HOW?

Answer 5

\(\sqrt{4(2x-1})=2\sqrt{2x-1}\)

Answer 6

oooooooooh so factor then simply the 4 , 2 is its qrt so it goes outside the sqrt

Answer 7

Thanks yall :)
