Answer:
domain: -2 < x < 4
range: -∞ < y < 9
Step-by-step explanation:
domain: because the domain is all of the x-values, just look for the furthest one to the left, which is -2, and then look for the one that is furthest to the right, it being 4.
range: because the quadratic function has the two arrows continuing downwards, toward the negative portion of the graph, it would be -∞. Then look for the maximum of the graph, which would be considered the most highest part of the graph, which is seen on the graph as 9.

Answer:
x = 24°
Step-by-step explanation:
To find 'x', the Alternate Exterior angle postulate will need to be used.
'4x + 9' and '2x + 27' are alternate exterior angles. Therefore, they must sum up to 180.
180 = 4x + 9 + 2x + 27
Combine like terms:
180 = 6x + 36
144 = 6x
x = 24°
