Pre-calculus: a student was given the piecwise function (image) and created this graph of the function. is the student's graph a correct representation of the function? if not, explain how it should be corrected.

  see the corrected graph below

Step-by-step explanation:

For starters, the solid and open dots need to swap places. The "or equal to" is not present for the middle segment, only the end segments.

Then the function for x ≥ 1 needs to be properly graphed. it is only defined on the interval 1 ≤ x < 3, so should will extend beyond x=3.

The correct answer is option C and D.

C). DC = 6√3

D). AC = 12√3
