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

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
