1.Y= x^2+4b+5

2. $latex y=ax^2+bx+c   B)the lines start at zero and are at the same points on the Y axes forever.

3.A) yes it has a maximum point and the point is zero is zero.

B) its minimum point is zero and its maximum is going above zero forever.

C)it has no maximum or minimum point


4.If a is positive the minimum is zero if it is negative the maximum is zero.

5. it change the line when B is negative 0 – -1 and when positive it will move to the left of the graph.
