To find g(-1) for the function g(x) = 2x^2 - 3, we need to substitute -1 for x in the function.

Start by calculating -1 squared:

(-1)^2 = 1.

Next, multiply this result by 2:

2 * 1 = 2.

Now, subtract 3 from this result:

2 - 3 = -1.

Therefore, g(-1) equals -1.

Since the calculated result does not match the selected answer, we can clarify that the correct computation shows that g(-1) evaluates to -1.
