How would you explain the relationship between
the real zero(s) of the function and x-intercept(s) of
the graph?
Since the graph crosses the x-axis at x = -2,
the function has a real zero of x = -2.
Since the graph never crosses the x-axis, the
function has no real zeros.
Since the graph eventually crosses the x-
axis, the function has a real zero.
Since the graph crosses the y-axis at 9, the
function results in a real zero of x = 9?.
