Compare the functions shown below:
f(x)
polynomial graph with x intercepts at negative 3, negative 2, 1, 2, y intercept at negative 12
g(x)
trig graph with points at 0, 3 and pi over 2, 0 and pi, negative 3 and 3 pi over 2, 0 and 2 pi, 3
Over the interval x = 0 to x = 2π h(x) = 2x3 − 2x2 − 3x + 2
Which function has the most x-intercepts?
f(x)
g(x)
h(x)
All three functions have the same number of x-intercepts.
