For two functions, a(x) and b(x), a statement is made that a(x) = b(x) at x = 2. What is definitely true about x = 2?

Both a(x) and b(x) have a maximum or minimum value at x = 2.
Both a(x) and b(x) have the same output value at x = 2.
Both a(x) and b(x) cross the x-axis at 2.
Both a(x) and b(x) cross the y-axis at 2.

 Both a(x) and b(x) have a maximum or minimum value at x = 2.
 Both a(x) and b(x) have the same output value at x = 2.
 Both a(x) and b(x) cross the x-axis at 2.
 Both a(x) and b(x) cross the y-axis at 2.

anonymous · Answer

The answer is  Both a(x) and b(x) have the same output value at x = 2. because when a(x)=b(x) the lines intersect at that point lines intersect they have a point in common. Also, a(x)=b(x) means that the outcomes are the same
