To graph the expression \( y = 2(5 - 3x^3) - 6 + 9x^{11} \), we will first simplify it:
-
Distribute the 2: \[ y = 2 \cdot 5 - 2 \cdot 3x^3 - 6 + 9x^{11} \] \[ = 10 - 6 + 9x^{11} - 6x^3 \]
-
Combine the constant terms: \[ y = 4 + 9x^{11} - 6x^3 \]
Now the equation is simplified to: \[ y = 4 + 9x^{11} - 6x^3 \]
Graphing the Function
To graph the function \( y = 4 + 9x^{11} - 6x^3 \), you can follow these steps or use software/graphing calculators:
- Determine key points: Evaluate the function at various values of \( x \) (for example, -2, -1, 0, 1, 2) to find corresponding \( y \) values.
- Identify end behavior: As \( x \) approaches large positive or negative values, the \( 9x^{11} \) term will dominate, leading to \( y \) heading towards positive infinity as \( x \) increases and also negative infinity as \( x \) decreases.
- Sketch the graph: Plot the calculated points and sketch the curve. The function will be very steep for larger absolute values of \( x \) due to the \( x^{11} \) term.
Summary of Behavior
- The graph will be a polynomial of degree 11.
- It will have a general shape that rises steeply for large (positive) \( x \) and drops heavily for large (negative) \( x \).
- The presence of the \( -6x^3 \) term will influence the shape and may create local minima/maxima, but for most \( x \), the \( 9x^{11} \) term will dominate.
Graphing can be done effectively using graphing software or a graphing calculator for more precise points and visualization.
