Question: I have tried this question, but I always get stuck!
Let f(x) = (2x2+3x-17)/(x+5)
Thank-you for your help,
Imagine that you have a button on your calculator labeled (2x2+3x-17)/(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 (2x2+3x-17)/(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
2) try to divide by zero.
For the second part I would first find all x for which f'(x) = 0.Cheers,
