The x-intercepts are indeed -1 and 1.
The increasing intervals are listed as (-1, 0) u (1, infinity) not because -1 and 1 are not included points of the function, but because the function is not differentiable in those points, so you can't tell whether the function is increasing or decreasing there.
Your best bet would be __ × 7= 56, where the blank space represents the amount of vans needed to take the students to the game.
-Hope this helps!

Step-by-step explanation:
What is the equivalent radian measure of a 260 degree angle?
Multiply 260 degrees by the conversion factor (π radians) / (180 degrees):
260 degrees π radians
----------------------- * --------------------- = 13/9π radians, or 1.444.... π radians
1 180 degrees
$260 because if there are two children you do 2x25=50 then 2x3=6 then 6x35=210 and then add 50 and 210 and you get 260
