of(x) has one real zero at -2 because the graph of the
function has an intercept at (0, -2).
Of(x) has two real zeros at-4 and -2 because the
graph of the function has intercepts at (4,0) and (0, -
2).
Of(x) has no real zeros because the graph of the
function does not pass through (0,0).
Of(x) has one real zero at -4 because the graph of the
function has an intercept at (-4, 0).
