The vertex is (2, -3).
Use the formula x= -b/2a to find the x value., which is 2.Then, substitute it into the function, wherever you see an x. Follow order operations and you get y, which is -3.

Answer:
y = 102, z = 67
Step-by-step explanation:
The angles 113 and z form a straight angle and are supplementary, thus
z = 180 - 113 = 67
The sum of the 4 interior angles of a quadrilateral = 360°
Sum the interior angles and equate to 360 for y
y + 102 + 89 + 67 = 360, that is
y + 258 = 360 ( subtract258 from both sides )
y = 102
