Answer:
The solutions listed from the smallest to the greatest are:
x:

y: -1 1 -1 1
Step-by-step explanation:
The slope of the tangent line at a point of the curve is:


The tangent line is horizontal when
. Then:



, for all 
, for all 
The first four solutions are:
x:

y: 1 -1 1 -1
The solutions listed from the smallest to the greatest are:
x:

y: -1 1 -1 1
34 + x = 63
x = 63-34
x = 29
95/100 = 0.95 <== if she missed 5 out of 95, then she got 95 out of 100
Step-by-step explanation:
