Find the zero of the function:
(if your answer is a fraction, input the fraction NOT the decimal)
HINT!!!...set y = 0 then solve for x...note this does NOT follow the rules for rational functions
(this is NOT p(x)/q(x)) since there's an extra -2 at the back of the equation)...just sub a 0 in for y and solve for x here to find the zero.
