For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. what is definitely true about x = 7?

I answered this recently.

Choices were:
A)Both m(x) and p(x) cross the x-axis at 7. 
B)Both m(x) and p(x) cross the y-axis at 7. 
C)Both m(x) and p(x) have the same output value at x = 7. 
D)Both m(x) and p(x) have a maximum or minimum value at x = 7.

The true statement was Choice C. Both m(x) and p(x) have the same output value at x = 7. 

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

Ican’t sorry i would if i could
