How many roots do the functions have in common?
f(x)=2x2−4x−16
A coordinate plane. The x- and y-axes both scale by one. The graph is the function y equals g of x which is a parabola that opens up. The function has an x-intercept at negative two, zero, a y-intercept at zero, negative four, a minimum around one, negative four point five, and another x-intercept at four, zero.
