Question

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

Answer 1

r (x ) = -x - 7

To find r(-2)

substitute x = -2 in the function

r(-2) = -(-2) - 7 = 2 - 7 = -5

To find r(0)

substitute x = 0 into the function given

r(0) = - 0 - 7 = -7

To find r(5), substitute x = 5 into the function

r(5) = - 5 - 7 = -12
