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 xaxis at 2.
Both a(x) and b(x) cross the yaxis at 2.

Best ResponseYou've already chosen the best response.0Well, do they tell you what a(x) or b(x) equal besides each other?

Best ResponseYou've already chosen the best response.0For instance a(x) = x*1 would mean that Both a(x) and b(x) cross the y axis at 2 when x = 2

Best ResponseYou've already chosen the best response.0It is hard to say without knowing what a(x) or b(x) equals other than each other. We know a(x) = b(x) but do you have anything else one of them might equal?

Best ResponseYou've already chosen the best response.0If a(x) or b(x) is a quadratic then it is a different story. It seem like you are missing something in your problem. Did you type it in right?

Best ResponseYou've already chosen the best response.0Never mind. I think they just want to know what is true when x = 2 and that would be C

Best ResponseYou've already chosen the best response.0They're asking which one is DEFINITELY true. All of them can be true under the right circumstances. a(x) = b(x) at 2 means a(2) = b(2), meaning they have the same y (or output) at x = 2

Best ResponseYou've already chosen the best response.0That is what I was getting to at first peachpi but then it stats What is definitely true about x = 2 and what is definitely true is when x = 2 it will be a vertical line at 2 so I figure they want you to chose C

Best ResponseYou've already chosen the best response.0we don't know that it's a vertical line. We don't know anything except that two function have the same y at x = 2. The only thing consistent is that they have the same y dw:1437791284212:dw

Best ResponseYou've already chosen the best response.0Yep that is right peachpi. I completely over looked that.

Best ResponseYou've already chosen the best response.0If a(x) = b(x) they both are going to have the same output when the input is 2
