Question Analysis
This question evaluates the student's understanding of vertical stretches applied to a cubic polynomial. The original function is stretched vertically by a factor of 5, which means every output value of the function is multiplied by 5.

Key Concept Explanation
A vertical stretch or compression of a function is a transformation that changes the shape of the graph by multiplying the output values by a constant. If the constant , the graph is stretched vertically.

Step-by-step Solution
1. Identify the original function:
2. Apply the vertical stretch by a factor of 5:
3. Substitute
