Solving the expression results to
a. N(-2) = 1 1/3
b. N(0) = 2/3
c. N(5) = -1
How to find the function
The function is solved by substitution as required
According to the problem we have the equation N(x) = -1 -1/3x + 1 2/3
rearranging the equation results to
N(x) = -1/3x + 2/3
a. For x = -2
N(-2) = -1/3 (-2) + 2/3
N(-2) = 2/3 + 2/3
N(-2) = 4/3
N(-2) = 1 1/3
b. For x = 0
N(0) = -1/3 (0) + 2/3
N(0) = 0 + 2/3
N(0) = 2/3
c. For x = 5
N(5) = -1/3 (5) + 2/3
N(5) = -5/3 + 2/3
N(5) = -1
