Question

is the function f(x)=x^2 increasing on decreasing at x = -1.

can anyone please check my reasoning:
the value of the derivative of the function at x=-1 is -2, so that means the slope of the tangent line to the graph at that is a negative value so the function is decreasing at x = -1.
Correct!
