Answer:
Vertex: (5, -9)
Step-by-step explanation:
fix = (x-8)(x-2)
fix = x^2 - 2x - 8x + 16
fix = x^2 - 10x + 16
a = 1, b = -10, and c = 16
To find vertex:
x = -b/2a
x = -(-10)/2(1)
x = 10/2
x = 5
y = 5^2 - 10(5) + 16
y = 25 -50 + 16
y = -9
Vertex: (5, -9)
No, it is not a function. It fails the vertical line test (VLT). VLT state that if you draw a vertical line, it must only intersect the graph one time. If it intersections more than once, then it is not a function.
The answer is (C) 52 degrees.
