LOOK AT PHOTO, please help! Alan is a software salesman. Let be Alan's total pay (in dollars). Let be the number of copies of History is Fun he has sold. Alan has copies available to sell. Suppose that gives as a function of for these available copies. Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

the correct answers i think are b. and d.

give me brainliest if it is correct!

the answer is a beach is the best place to be
