Question

Which function has x-intercepts of 3 and 8 and contains the point (–1, –2)?

Answer 1

x intercept would be the point for which Y=0.
all the functions given have x=3,and x=8 as x-intercept.
put x=1 and y=2 in all of the equations for the equation whose right and left sides would be equal is the required result you are looking for.

for example if i put x=1 and y=2 in first equation
2=−136(1−3)(1−8)

this gives
2=1436

2=718

since 2 is not equal to 7/18 so its not the answer.
do the same for remaining options for which you get
2=2 would be the proper answer.
