Evaluate n (x) = -1-x+4 when x=-2,0, and 5

Step-by-step explanation:

n (-2) = - 1 - (-2) + 4 = - 1 + 2 + 4 = - 1 + 6 = 5

( - 1, 6 one has + sign and other - sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [6] is +. So, result is 5)

n (0) = - 1 - 0 + 4 = - 1 + 4 = 3

n (5) = - 1 - 5 + 4 = - 6 + 4 = - 2

(-6, 4 one has + sign and other - sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [-6] is -. So, result is - 2)
