Which word best describes the range of a function? input output independent relation

Output

Step-by-step explanation:

A function takes values of x (the horizontal axis on a plane)and returns the corresponding values of y (the vertical axis on a plane).

Thus, the values we get for y depends on the value of x.

The x's values that we give in a function are called the domain, and the values that the function returns to us are called the range of the function (the y's).

So a word that describes the range of a function well is that the range is the output of the function. Because the range is the set of values that the function returns to us when we plug an x value.

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
