Question

W (n) = n^2-n find w (-3)

Answer 1

`w(-3) = 12`

Explanation:

Plug in -3 for n in the equation:

`w(n) = n^2 - n`

`w(-3) = (-3)^(2) - (-3)`

Simplify. Remember to follow PEMDAS. First, solve the power:

`w (-3) = (-3)^2 - (-3)\\w (-3) = (-3 * -3) - (-3)\\w (-3) = (9) - (-3)`

Next, combine like terms. Note that if there are two negative signs directly next to each other, it becomes a positive sign. Add:

`w(-3) = 9 - (-3)\\w(-3) = 9 + 3\\w(-3) = 12`

Your answer:
`w(-3) = 12`
