Question

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

Answer 1

Answer:

$w(-3) = 12$

Step-by-step 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: $w(-3) = 12$
