Use the graph of f(x) to explain the relationship between
he real zeros of f(x) and its intercept(s).
f(x) has one real zero at -2 because the graph of the
function has an intercept at (0, -2).
f(x) has two real zeros at -4 and -2 because the graph
of the function has intercepts at (-40) and (0.-2).
f(x) has no real zeros because the graph of the function
does not pass through (0,0).
f(x) has one real zero at -4 because the graph of the
function has an intercept at (-4, 0).
