Zeros of this function are not real, this is because if we’re using the quadratic formula our discriminant has to be positive to produce any real number as a solution. In this case our discriminant is -4 using the formula B^2-4AC.
The true statement about the graph of the function f(x) = x3 - 2x2 + 4x – 8 is (B) The function has 1 real zero that occurs 1 time.
<h3>How to determine the true statement</h3>
The function of f(x) is represented as:
Differentiate the function f(x)
Calculate the minimum value using:
So, we have:
Substitute 2/3 in f'(x)
The value of f'(2/3) is greater than 0.
This means that the function f(x) has 1 real zero, and it occurs once at point (2,0)
Hence, the true statement is (b)

Answer:
Response bias
Step-by-step explanation:
Response bias means: anything in a survey that influences responses. In this situation the question is "Do you favor harsher penalties for individuals who sell guns illegally?" The person is asking a very specific question rather than allowing it to be broad. The scenario is that the surveyor wanted tot estimate the percentage of people who favor just stricter gun laws in general and not within the limits of illegally sold guns. If he were to ask "Do you favor stricter penalties for buying/selling guns?" then it would fit the guidelines of the initial estimate. hope this makes sense :)
