Question

I am very confused about functions. I think if I could see this example, then I'll be good. f(x)=x^2 and g(x)=5x. I am supposed to find f (little circle that's used in Danish...what's it called in math terms?) g, and g little circle f. Thank you so much.

Answer 1

I think you want f[(g(x)] and g[f(x)]

f[g(x)] is (5x)^2 = 25x^2
g[f(x)] is 5*x^2 = 5 x^2
