Transcribed Image Text:**Problem Statement:**
Find the equation of this quartic that goes through the point (0, -2).
**Graph Explanation:**
The graph is a smooth curve representing a quartic (fourth-degree polynomial) function. It shows the behavior of the polynomial across a range of x-values from -5 to 6.
**Key Features of the Graph:**
- The x-axis ranges from -5 to 6.
- The y-axis ranges from -5 to 3.
- The curve has two turning points, visible around x ≈ -3 and x ≈ 3.
- The curve passes through the point (0, -2) as specified.
- It starts from the top left, dips down, and then rises towards the center before dipping again slightly and rising back up as it moves towards the right.
- The end behavior indicates that as x → ±∞, the graph rises in both directions, common for a quartic function with a positive leading coefficient.
**Understanding the Graph:**
The objective is to find an equation in the form \( y = ax^4 + bx^3 + cx^2 + dx + e \) that matches the curve and passes through the given point.
This graph’s characteristic shape can be used to deduce such a polynomial by considering key points, intercepts, and the graph's symmetry.
