    Please help me with this function.

    b(X) = X^2 + 3

    find / simplify b(a+h) -b(a) / h

    I thought I knew how to do this, but the function of X is confusing me since there is no X variable in the Find.

    \frac{(a+h)^2 + 3 - (a^2+3)}{h}

    expand the numerator and combine like terms, then factor ... you should get the h in the denominator to divide out
