Question 1006791: Combining functions with (f*g)(x) and (f*g)(4):
f(x)= sqrt(4x-1) g(x)=x^2-10
I've tried sqrt(4x^2-1-10)
But, I didn't know how I would multiply that by 4, so it doesn't seem right.

I'm assuming when you write (f*g)(x), you really mean "f times g of x" and it is NOT function composition. If it is function composition, then please let me know.
