Identify the range of the function shown in the graph. A.–6 ≤ x ≤ 6
B. y is all real numbers.
C.0 ≤ y ≤ 8
D. y > 0

The answer is A

the triangle is highlighted around -6 and 6 on the x axis

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
