Which equation, when graphed, has x-intercepts at (2, 0) and (4, 0) and a y-intercept of (0, –16)?
f(x) = –(x – 2)(x – 4)
f(x) = –(x + 2)(x + 4)
f(x) = –2(x – 2)(x – 4)
f(x) = –2(x + 2)(x + 4

f(x) = -2(x - 2)(x - 4)
Reason: For roots 2 and 4, f(x) = a(x-2)(x-4). f(0) = a(−2)(−4) = 8a = −16 ⇒ a = −2.
