Answer:
[tex]w(-3) = 12[/tex]
Step-by-step explanation:
Plug in -3 for n in the equation:
[tex]w(n) = n^2 - n[/tex]
[tex]w(-3) = (-3)^{2} - (-3)[/tex]
Simplify. Remember to follow PEMDAS. First, solve the power:
[tex]w (-3) = (-3)^2 - (-3)\\w (-3) = (-3 * -3) - (-3)\\w (-3) = (9) - (-3)[/tex]
Next, combine like terms. Note that if there are two negative signs directly next to each other, it becomes a positive sign. Add:
[tex]w(-3) = 9 - (-3)\\w(-3) = 9 + 3\\w(-3) = 12[/tex]
Your answer: [tex]w(-3) = 12[/tex]
