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.
O
Since the graph never crosses the x-axis, the
function has no real zeros.
O
Since the graph eventually crosses the x-
axis, the function has a real zero.
nce the graph crosses the y-axis at 9, the
1
function results in a real zero of x = 9 ?.
