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.

MathMate,
Correct!
