Question

8. The factored form of a polynomial function isf(x) = x(2x - 5)(x + 3). Which statement correctly

describes the graph of the polynomial function?
A. The graph intersects the x-axis at the
B. The graph intersects the x-axis at the points (-2.5, 0) and (3, 0) and (0, 0).
C. The graph intersects the y-axis at the points (0, – 2.5) and (0, – 3) and (0, 0).
D. The graph intersects the y-axis at the points

Answer 1

Graph intersect at x -axis with points is ( 0 , 0) , (2.5 , 0) and ( - 3 , 0 )

Explanation:

Given function as ,

F(x) = x(2x - 5)(x + 3)

i.e Y is a function of x

So ,At y = 0 , x =0

y = 0 , x =
`(5)/(2)` = 2.5

y = 0 , x = - 3

i,.e Graph intersect at x - axis ,

So the points is ( 0 , 0) , (2.5 , 0) and ( - 3 , 0 ) Answer
