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