Given f(x) = x^2 - 36, which statement is true? Graph the expression and graph the answer choices. Analyze the graphs to see which one makes an exact match.

• The only zero, 6, can be found when 0 = (x - 6)(x - 6).

• The only zero, 18, can be found when 0 = (x - 18)(x - 18).

• The zeros, -6 and 6, can be found when 0 = (x + 6)(x - 6).

• The zeros, -18 and 18, can be found when 0 = (x + 18)(x - 18).
