Answer:
f(0) = 1/2
Step-by-step explanation:
At x=0, the inequality tells you ...
1/2 ≤ 1 -f(0) ≤ 1/2
That is, ...
1 - f(0) = 1/2
f(0) = 1/2

(-2.5,6.1)(-2.5,3.1).....notice how ur x values are the same. This means that u have a vertical line which has an undefined slope.
IF ur y values would have been the same, u would have had a horizontal line which has a 0 slope.
Nina's rate is 12.7 mph and Sophia's rate is 10 mph. Therefore, Nina is faster.
The answer is A.
The 0's of the function are -2, 2, and 3.
The graph starts from the bottom left and it keeps going to the top right.
