Even though we have not defined these terms mathematically, one likely answered that f f is increasing when x > 1 x > 1 and decreasing when x < 1 x < 1. We formally define these terms here.Now as to whether the speed is increasing or decreasing at t = 6. The change in speed at t = 6 would be the derivative of the curve at that point, but since the curve has a sharp point in t = 6, the derivative is undefined. That's because on the left side, the slope is getting more and more negative.A critical point is when the derivative equals 0. And while it is always negative where you indicated, the derivative itself is increasing at one point. A much easier example to see this is -x^2. if this were the derivative of something, this also has a critical point at (0,0).Pre Calculus Equations Inequalities Scientific Calculator Scientific Notation Arithmetics Complex Numbers Polar/Cartesian Simultaneous Equations System of Inequalities Polynomials Rationales Functions Arithmetic & Comp.
