To find the number of turning points for the function \( g(x) = 3x^3(x - 5)^2(5 - x)^4 \), we first need to identify the degree of the polynomial and the behavior of the function at its critical points.
-
Determine the degree of the polynomial:
- \( 3x^3 \) contributes a degree of 3.
- \( (x - 5)^2 \) contributes a degree of 2.
- \( (5 - x)^4 \) contributes a degree of 4.
So, the total degree of the polynomial is: \[ 3 + 2 + 4 = 9 \]
-
Finding the maximum number of turning points: The maximum number of turning points a polynomial can have is one less than its degree. Therefore, for a polynomial of degree 9, the maximum number of turning points is: \[ 9 - 1 = 8 \]
Thus, Rogelio's sketch of the graph of \( g(x) \) should include at most 8 turning points.
So, the correct answer is: eight at most.
