Answer:
B. The function has an even degree.
Step-by-step explanation:
We have been given an image of a polynomial function. We are asked to choose the correct options about our given polynomial.
A. The function has a negative leading coefficient.
Upon looking at our given graph, we can see that it is an upward opening parabola, so leading coefficient can't be negative, therefore, option A is not true.
B. The function has an even degree.
Upon at our given graph, we can see that it is symmetric to y-axis, therefore it has an even degree polynomial and option B is the correct choice..
C. The function has zero turning points.
Upon looking at our given graph, we can see that as function approaches towards 0 from negative infinity it is decreasing. As function increases positive infinity from 0, it is increasing, therefore, our function has a turning point at , therefore, option C is incorrect.
D. The function has one x-intercept.
Since our function never intersects x-axis, therefore, function has no x-intercept and option D is incorrect as well.
The fraction of the red haired students are boys will be 2 / 5.
<h3>What is a fraction number?</h3>A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
The dual bar chart shows the hair colour of boys and girls in a year group.
The total number of the boys and girl will be
Total = 6 + 9
Total = 15
Then the fraction of the red haired students are boys will be
⇒ 6 / 15
⇒ 2 / 5
