WebIn calculus we learn that if the DERIVATIVE of a function is positive on an interval, then the function is increasing on that interval. If the DERIVATIVE of a function is negative on an interval, then the function is decreasing on that interval.

WebThus, since the derivative increases as x increases, f ′ is an increasing function. We say this function f is concave up. Figure 4.34 (b) shows a function f that curves downward. As x increases, the slope of the tangent line decreases. Since the derivative decreases as x increases, f ′ is a decreasing function. optiphos wspWebThe slope determines if the function is an increasing linear function, a decreasing linear function, or a constant function. f(x) = mx + b is an increasing function if m > 0. f(x) = mx + b is a decreasing function if m < 0. f(x) = mx + b is a constant function if m = 0.
