Answer:
2
Explanation:
Given the function:
[tex]f\mleft(x\mright)=(x^2-5x+4)\left(x\right)[/tex]
The greatest power of f(x) = 3.
This means that the polynomial f(x) is a cubic polynomial.
The number of turning points in a cubic polynomial is 2.
A graphical illustration is attached below:
Thus, the number of turns in the graph of the function f(x) is 2.
