find (f of g)x=3, (f of g)x, (f of g)(x)=f[g(x)], f(x)=x2-9,

[mclevel2]

can anyone help me solve this formula
f(x)=x2-9 & g(x)=x+5
find (f of g)x=3
find (f of g)x (f of g)(x)=f[g(x)]

Since you refer to "solving a formula", I will guess that you are not familiar with the necessary concepts or terminology, so please start by reading at least two lessons on composition of functions.

(I'm assuming the formatting of the exercise involves typoes, and that you have learned about function notation. So, for instance, "(f of g)x=3" means something like "evaluate (f o g)(x) at x = 3" or "solve f(g(x)) = 3 for x".)

f(x)=x2-9 & g(x)=x+5
find (f of g)x=3
find (f of g)x (f of g)(x)=f[g(x)]

Once you have studied some lessons and have learned the background material, please attempt the exercise. If you get stuck, please reply with clarification of the exercise, using standard formatting, and provide a clear listing of your steps and reasoning so far.

Thank you!
