Question

Need help on one question and just want someone to check my answer on another

Answer 1

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y = \[4/x^2 +9\]
f(x) = x + 9 g(x) = \[4/x^2\]
f(x) = x g(x)=\[4/x +9\]
f(x) = \[1/x\] g(x) = \[4/x +9\]
f(x)= \[4/x^2\] g(x) = 9

Answer 2

I think this one is C

Answer 3

f(x) = Square root of quantity three x plus seven. , g(x) = Square root of quantity three x minus seven..

Find (f + g)(x).

Square root of six x. <-------

x Square root of six.

3x

Square root of quantity three x plus seven. +Square root of quantity three minus plus seven.
