Over Which Interval Is The Graph Of F(X) = –X2 + 3X + 8 Increasing?
Introduction
Understanding the concept of increasing and decreasing intervals of a graph is an important mathematical skill to have. Knowing when a graph is increasing or decreasing can help you in solving many problems and make it easier to understand the overall pattern of a function. In this article, we will discuss what it means for a graph to be increasing or decreasing, and then apply that knowledge to the specific example of the graph F(x) = −x2 + 3x + 8. We will also explore how such concepts can be used more broadly in mathematics.
The graph of F(x)
The graph of F(x) is increasing over the interval [-1, 1].
The interval over which the graph is increasing
Assuming we are talking about the interval of a graph on the x-axis, the graph is increasing over the interval between -1 and 1. So, if we take any two points within that range, such as -0.5 and 0.5, the line will be going up as it passes through those points.
Conclusion
In conclusion, the graph of F(x) = –x2 + 3x + 8 is increasing over the interval (-∞, 2]. This result was obtained by calculating the critical points and then analyzing where the tangent line to each point had a positive slope. Analyzing functions like this can be difficult at first but with practice it becomes easier. As always, graphing tools are also helpful when trying to determine whether or not a function is increasing or decreasing on a given interval.
