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)

Respuesta :

the zeros are 2 and 4, so obviously either A or C, (eliminate B and D which have zeros of -2 and -4.)
the y intercept is -16. Plug x=0 in A and C to see which equation produce a result -16. C is correct.
