The image of a parabolic lens is traced onto a graph. The function f(x) = (x + 8)(x – 4) represents the image. At which points does the image cross the x-axis?
A.(–8, 0) and (4, 0)
B.(8, 0) and (–4, 0)
C.(2, 0) and (–1, 0)
D.(–2, 0) and (1, 0)
The right answer for the question that is being asked and shown above is that: "B.(8, 0) and (–4, 0).' The image of a parabolic lens is traced onto a graph. The function f(x) = (x + 8)(x – 4) represents the image. At B.(8, 0) and (–4, 0) points does the image cross the x-axis.
