2.36 ### Understanding Function Intervals: Increasing, Decreasing, and Constant**Problem Statement:**Determine the open intervals on which the function is increasing, decreasing, or constant. (Enter your answers using interval notation. If an answer does not exist, enter DNE.)Given function: \( f(x) = x^2 - 4x \)**Intervals:**- Increasing: [Input field]- Decreasing: [Input field]- Constant: [Input field]**Graph Description:**The graph of the function \( f(x) = x^2 - 4x \) is a parabola that opens upwards. The vertex of the parabola is at the point \((2, -4)\).- The x-axis ranges from -2 to 6. - The y-axis ranges from -8 to 6.- The vertex at \((2, -4)\) indicates the minimum point of the function.### Analysis of the Graph:1. **Decreasing Interval:** - The function \( f(x) \) is decreasing on the interval where \( x \) is less than 2. This can be observed as the slope of the graph is negative (moving downwards) as it approaches the vertex from the left (from \( -\infty \) to 2).2. **Increasing Interval:** - The function \( f(x) \) is increasing on the interval where \( x \) is greater than 2. This is observed as the slope of the graph turns positive (moving upwards) as it leaves the vertex moving to the right (from 2 to \( \infty \)).3. **Constant Interval:** - There are no intervals where the function \( f(x) \) is constant. The function is either increasing or decreasing.### Final Intervals:- **Increasing:** \( (2, \infty) \)- **Decreasing:** \( (-\infty, 2) \)- **Constant:** DNEThese intervals are found by analyzing the vertex and the direction of the parabola.For further understanding, remember that the vertex form of a quadratic function \( ax^2 + bx + c \) can help you identify these intervals quickly:- The vertex \((h, k)\) can be found using \( h = -\frac{b}{2a} \).- The function is increasing on \( (h, \ This image shows a graph of a quadratic function, specifically a parabola. The parabola opens upwards, indicating that the coefficient of the squared term \( x^2 \) is positive.### Details:- **Axes:** - The horizontal axis is labeled as \( x \). - The vertical axis is labeled as \( y \).- **Points of Intersection:** - The parabola intersects the \( y\)-axis between -2 and -4. - The parabola intersects the \( x\)-axis near 5 and -1.- **Vertex:** - The vertex of the parabola, the lowest point on the graph, is labeled as \( (2, -4) \).The graph clearly depicts a quadratic equation in the form \( y = ax^2 + bx + c \). The specific values of \( a \), \( b \), and \( c \) are not provided in the image. The vertex form of this quadratic equation can be expressed as \( y = a(x - h)^2 + k \), where \( (h, k) \) is the vertex of the parabola. For this graph, the vertex is \( (2, -4) \), leading to the vertex form \( y = a(x - 2)^2 - 4 \).Understanding how to read such graphs is crucial for analyzing quadratic functions, which are commonly encountered in various fields of mathematics and science.
