Homework Equations
lim x->a[tex]\frac{f(a+h)-f(a)}{h}[/tex]
The Attempt at a Solution
Ive tried so many times to figure this out. I first substituted the equation into the formula above and multiplied by the conjugate and ended up removing h from the numerator and denominator leaving a -1/2[tex]\sqrt{a}[/tex]. As you can see I have already lost credit for the problem and cannot redo it, but I still want to know how to do it. Any tips and help is appreciated.
