How do we know a function is increasing
WebThe function would be positive, but the function would be decreasing until it hits its vertex or minimum point if the parabola is upward facing. If the function is decreasing, it has a negative rate of growth. In other words, while the function is decreasing, its slope would … Let me stick it right over here. There we go. Got it right. Let's do a couple more. So … 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.
