- D) f(x) = (x - 1)(x - 2)(x - 3)
Step-by-step explanation:
Given
- Graph of the function
To find
- The function in factored form
According to graph we observe:
- the function has 3 roots at x = 1, 2, 3;
- the function is of odd degree;
- the function is increasing, so the coefficient is positive
This gives us the function:
- f(x) = (x - 1)(x - 2)(x - 3)
The matching answer choice is D
