Question

A local maximum of the function f(x) occurs for which x-value? -4 -3 -2 -1

Answer 1

My guess is -1 because when a x value don’t got a number replace it with a 1

Answer 2

I think the answer would be -1 because normally you would place a 1 in front of x if it was negative, so I’m assuming you would do the same if it was -x and the one would just go after the negative symbol
