Answer:
End behavior of a polynomial function depended on the degree and its leading coefficient.
1. If degree is even and leading coefficient is positive then


2. If degree is even and leading coefficient is negative then


3. If degree is odd and leading coefficient is positive then


4. If degree is odd and leading coefficient is negative then


(a)

Here, degree is even and leading coefficient is positive.


(b)

Here, degree is even and leading coefficient is negative.


(c)

Here, degree is odd and leading coefficient is positive.


(d)

Here, degree is odd and leading coefficient is negative.


The answer will just be pi
Well, 20% is equivalent to (1/5). So, you'd put 50 in the numerator and 5 in the denominator. (50/5) is equal to 10. Then you'd take that value and subtract it from your original value. [ 50 - 10 = 40 ]. 40 Students were at school that day.
