Evaluate r(x) = -x -7 when x = -2, 0, and 5

The values of r(x) for x = - 2, 0 and 5 are obtained by Substituting the values for x in the function, hence the values are :

When x = - 2

When x = 0

When x = 5

Therefore, the required values are - 9, - 7 and - 2

r(-2) = -5 , r(0) = -7 , r(5) = -12

Step-by-step explanation:

Plug in the numbers for x and then solve. : )

r(-2) = - (-2) - 7

r(-2) = 2 -7

r(-2) = -5

r(0)= -0 -7

r(0)=0-7

r(0) = -7

r(5) = -5 - 7

r(5) = -12

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
