Question

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

Answer 1

I think it is A but I'm confused

Answer 2

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
\[\Large 2=\frac{-1}{36}(1-3)(1-8)\]
this gives
\[\Large 2=\frac{14}{36}\]
\[\Large 2=\frac{7}{18}\]
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.
