Who is asking: Student Question: I have tried this question, but I always get stuck!
Let f(x) = (2x^{2}+3x17)/(x+5)
Thankyou for your help, Imagine that you have a button on your calculator labeled (2x^{2}+3x17)/(x+5). It works like the square root button. Input a number, call it x, then press this button and the calculator shows the value of (2x^{2}+3x17)/(x+5). For what values of x does this button give an error message? I know that my calculator gives an error message if I or 2) try to divide by zero. For the second part I would first find all x for which f'(x) = 0. Cheers,Harley
