Function Question!!!!!!!!

Answer 1

Choice A) The vertical line test confirms that the graph is a function
True. It is impossible to pass a single vertical line through more than one point on this graph. 
--------------------------------------------
Choice B) The domain is x >= 2
False. The domain is the set of all real numbers
--------------------------------------------
Choice C) The range is y >= 2
True. The smallest y value possible is y = 2. This is where the lowest part of the graph occurs.
--------------------------------------------
Choice D) This piecewise function is made up of four intervals
False. There are two intervals (the curved one on the left; the straight piece on the right)
--------------------------------------------
Choice E) Each interval of the piecewise function contains a graph of a linear function.
False. While the piece on the right is linear, the left portion is nonlinear (curved piece).
--------------------------------------------
In summary we have:

choice A) true
choice B) false
choice C) true
choice D) false
choice E) false

So the answers are choice A and choice C
