First answer gets brainiest answer

a. the vertical line test confirms that the graph is a function
b. the domain is x2
c. the range is y2
d. this piecewise function is made of 4 intervals
e. each interval of the piecewise function contains a graph of a linear function

A is true.  There is no vertical line that can intersect this graph twice.

B is false.  The function is defined for all .

C is true.  The minimum value of is .

D is false.  The piecewise function is made of one semicircle and one line, just two functions.

E is also false.  The circular arc is a nonlinear function.

Thus, the answer is A and C.

From my calculations I did on a piece of paper, I came up with The vertical line test confirms that the graph is a function (which is option A.) and The range is y > 2 (which is option C.) 

The rest of your options are not true 

But,
