### Analysis of Graph Accuracy#### Question:Which of the following describes a correct analysis of the graph?#### Options:- **A.** It is safe to assume the graph is drawn correctly because (0, -8) is a solution of the equation, and it is part of the graph.- **B.** It is safe to assume the entire graph is drawn incorrectly because (-4, 0) is not a solution of the equation, and it is not part of the graph.- **C.** It is safe to assume the graph is drawn correctly because (5, -5) is not a solution of the equation, and it is not part of the graph.- **D.** It is safe to assume the graph is drawn incorrectly because (2, 4) is not a solution of the equation, and it is part of the graph.#### Explanation of the Graph:The given graph depicts a curve plotted on a Cartesian plane with x-axis and y-axis, showing both positive and negative values. Significant points are marked and the curve shows concave downward and upward sections, crossing both axes.- The graph crosses the y-axis at (0, -8).- The graph does not pass through (-4, 0).- The graph does not include the point (5, -5).- The graph does not include the point (2, 4).To determine the correctness of the graph, one needs to determine whether specific points lie on the curve defined by the graph.---Powered by LinkIt! ### Graphing Cubic Functions: An Example**Question 23:** Jonathan plots the graph of the equation $ y = 0.5x^3 + 3x^2 - 8 $.#### Explanation:Jonathan is tasked with graphing the cubic function $ y = 0.5x^3 + 3x^2 - 8 $.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

### Graphing Cubic Functions: An Example

**Question 23:** Jonathan plots the graph of the equation $ y = 0.5x^3 + 3x^2 - 8 $.

#### Explanation:

Jonathan is tasked with graphing the cubic function $ y = 0.5x^3 + 3x^2 - 8 $. Below, you will see the graph generated from this equation.

The graph shows a typical cubic function with the following characteristics:

1. **Axes and Grid Lines:**
- The graph is plotted on a Cartesian coordinate system with both x and y axes ranging from -10 to 10.
- The background grid helps in identifying key points and the general shape of the function.

2. **Cubic Function Behavior:**
- Cubic functions can have turning points and can cross the x-axis at multiple points.
- In this specific graph, starting from the left, the function begins in the fourth quadrant, increases to cross the x-axis and then decreases to a turning point. It then rises steeply as $ x $ becomes positive.

3. **Intercepts and Turning Points:**
- The graph intersects the y-axis at $ y = -8 $, suggesting the y-intercept is at (0, -8).
- The nature of the function includes a local minimum around $ x = -6 $ and a local maximum around $ x = 3 $.

The graph visually demonstrates the nature of cubic functions, including their turning points and overall shape. For educational purposes, such a graph is essential to understand the behavior and characteristics of polynomial functions.

**Technical Tools:**
- This graph was plotted using software powered by LinkIt!, which provides tools for interactive educational content.

For more detailed analysis, students can adjust the function parameters to see how changes affect the shape and position of the graph.
