Find the domain and range of the function
SVEN [57.7K]

Answer:

domain: (-∞ , ∞)

range: (-∞, 2]

Step-by-step explanation:

the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2

range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

What is the measure of BGD?
slamgirl [31]

Answer:

90 degrees

Step-by-step explanation:

Angle BGD is supplementary with angle DGE.

BGD + DGE = 180

Since angle DGE is a right angle, then Angle BGD must also be a right angle:

BGD + 90 = 180

BGD = 90
