Question

In the xy -plane, what is the y -intercept of the graph of the

equation y =2(x+ 3)(x- 4)?
A. 24
B. 12
C. 2
D. 12

Answer 1

I don't think the correct y-intercept is offered as one of the choices.

y = 2 (x + 3) (x - 4)

Where the graph crosses
the y-axis, x=0 : y = 2 (0 + 3) (0 - 4)

y = 2 ( 3 ) ( -4 )

y = 2 ( -12 ) = -24
