Answer:

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

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 :

  • r(-2) = -9
  • r(0) = -7
  • r(5) = -2

When x = - 2

  • Substitute the value of x = - 2 into the function r(x) = - x - 7

  • r(-2) = - 2 - 7 = - 9

When x = 0

  • Substitute the value of x = 0 into the function r(x) = - x - 7

  • r(-2) = 0 - 7 = - 7

When x = 5

  • Substitute the value of x = 5 into the function r(x) = - x - 7

  • r(-2) = 5 - 7 = - 2

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