Question

Select the ordered pair that represents a solution to each function below.

f (x) = -x^2 + 5

(-2, -17)
(-2, 1)
(-2, 8)
(-2, 4)
(-2, -1)
(-2, 9)

Answer 1

(-2, 1) b/c f(-2) = -(-2)² + 5 = -4 + 5 = 1

Answer 2

( -2 , 1) is correct answer.

Explanation:

Given : f (x ) = -x² + 5.

To find : Select the ordered pair that represents a solution to each function below.

Solution : We have given that

f (x ) = -x² + 5.

From the given options

For x = -2 ,

f(-2) = -(-2)² + 5.

f(-2) = -4 + 5.

f(-2) = 1

Then ( -2 , 1)

Therefore, ( -2 , 1) is correct answer.
