# Graph Intersections: f'(x) > g'(x) - Can It Intersect More Than Once?

• haxan7
In summary, the conversation discusses a multiple choice question in an exam about the intersection of two functions based on their derivatives. The correct answer is that the graphs will intersect only once, as the slopes will not follow the same inequality if they intersect more than once. This can be understood from a physics perspective, where the rate of change of one function must be greater than the other for them to intersect.

First of all i am new to this forum, and since my question is from my exam i did not post in homework section, if posted it in wrong section then kindly move it to right one.

So i had this mcq in exam it said that if f'(x)>g'(x) for all values of x.
then the graphs of two function intersect at.
(a) At only one point
(b)Many intersect more than once.

There were other options too but i did not mention them here because i know they were wrong.

I know that the graphs will intersect once, i want to know if it can intersect more than once.
