Answer:
3 or 4, I am confused
Step-by-step explanation:
I'll assume that f(x) = x2 – 2x + 8 is meant to be f(x) = x^2 – 2x + 8
Find the value of f(x) for x = 2:
f(x) = x^2 – 2x + 8
f(2) = (2)^2 – 2*(2) + 8
f(2) = 4 - 4 + 8
f(2) = 8
=============
From the graph, we can find that g(2) = 11
The differece between g(2) and f(2) is thus:
11 - 8 = 3
3 is not an option, so I wonder if the question is asking for the difference between the absolute maximum of g(x) and f(2). If so, the maximum for g(x) is 12, at x = 3.
This would lead to a difference of 12 - 8, or 4. This is still not an option, so I'm confused. Perhaps you can find my error and find the ciorrect answer, or at least one that appears in the options.

Step-by-step explanation:
Given
<em>The attachment presents the table properly</em>
Solving (a): Percentage of those who play for less than 50 hours weekly
To do this, we simply consider the frequency of students that fall within:
1.0 - 7.9, 8.0 - 14.9,......,43.0 - 49.9
Their frequency is:
The percentage is then calculated as:
Solving (b): Percentage of those who play for 43 or more hours weekly
To do this, we simply consider the frequency of students that fall within:
43.0 - 49.9,......,64.0 - 70.9
Their frequency is:
The percentage is then calculated as:
