Answer
$-13$
Work Step by Step
We start with the given expression: $2a-b^2+c$
We plug in values for $a$, $b$, and $c$: $2(-1)-(3)^2+(-2)$
We simplify according to the order of operations:
First, we simplify powers: $2(-1)-9+(-2)$
Then, we multiply: $-2-9+(-2)$
Finally, we add and subtract from left to right: $-11+(-2)=-13$
