hey guys,

I just want to check if i did these questions right, ym textbook doesn't have any examples of them, so there's no way for me to check

a) f(x) = sqrt(x+1)

g(x) = sqrt(x-1)

f*g

= sqrt(x+1) * sqrt(x-1)

= sqrt[(x+1)(x-1)]

= sqrt(x^2 - 1)

f/g

= sqrt(x+1) / sqrt(x-1)

= sqrt[(x+1)(x-1)] / x-1

thanks
