In need of assistance, the graphs and such are there, answer!

See explanation

Step-by-step explanation:

a. The domain of the function (all possible values of x) is

b. The range (all possible values of y) is

c. The graph is increasing (the graph goes up) for all

d. The graph is decreasing (the graph goes down) for all

e. The relative maximum (point at which for all left values of x graph is increasing and for all right velues of x graph is decreasing) is at point (-2,3);

f. There are no relative minimums (points at which for all right values of x graph is increasing and for all left velues of x graph is decreasing).

the answer is a if my teacher taught me correct

the value of x is 90 - 20 aka 70*, these are complementary angles
