Answer:
he can only serve 2
Step-by-step explanation: since 3.5 plus 3.5 is 7.0 if you add one more it turns to 7.0 plus 3.5 10.5 so the greatest he can serve is two people
Slope is always (y2-y1)/(x2-x1) in this case:
(-2-3)/(6--4)
-5/10
-1/2
If you have 60% out of 40 students that is 24 students
F(x)=x^2+3x+5
f(3+h)=(3+h)^2+3(3+h)+5
f(3+h)=9+6h+h^2+9+3h+5
f(3+h)=23+9h+h^2
