Function Notation: If ƒ(x²) = x² - 1 and g(x²) = 3x, calculate g(4)/ƒ(2)

Question

please help me!

If ƒ(x²) = x² - 1 and g(x²) = 3x, calculate g(4)/ƒ(2)

Answer 1

are you sure it is f(x^2) and g(x^2), that doesn't make sense

if it is f(x) and g(x) then for g(4) = 3(4) = 12

and f(2) = 2^2 - 1 = 3

then 12/3 = 4

so g(4)/f(2) = 4

Answer 2

Thank you so much!, and you are right, I didnt type it right, because im dyslexic!  here it goes again

 

If ƒ(x) = x²-1 and g(x) = 3x, calculate g(4) / ƒ(2)

 

Thank you so much Kmartin!
