Answer:
w(-3)=6
Explanation:
w(n)=n^2-3
w(-3)=-3^2-3
w(-3)=9-3
6
Fist you change the n to -3.
Next you multiply -3 times -3 and two negatives multipled together makes a positve so it would be 9.
Then you subtract 9 and 3 and yo get six.
P.S. if you have a number, for example 5, then there is a ^2 above the five, which means you multiply 5 by 5.
