Question 1009668: 1. How do you determine the y intercept of a function written in standard form?
2. How do you determine if a function written in vertex form has a maximum or minimum?
3. How do you find the axis of symmetry when a function is written in vertex form?

1. Let x=0 and solve for y. y-intercept is (0,y)
.
2. Vertex form:

If a is positive, the function has a minimum.
If a is negative, the function has a maximum.
.
3. Axis of symmetry: x=h
