Using graphing technology:

1) Graph y=x^2, and then experiment with adding different linear terms (for example, x^2 +4x, x^2+20x,x^2- 50x). Record your observations.


2) Graph y=-x^2, and then experiment with adding different linear terms. Record your observations.
Use your observations to help you complete the table without graphing the equations.

equation

x-intercepts

x-coordinate of the vertex

y=x^2+6x

y=x^2-10x

y=-x^2 +50x

y=-x^2-36x

Some quadratic expressions have no linear terms. Find the x-intercepts and the x-coordinate of the vertex of the graph representing each equation. (Note it is possible for the graph to not intersect the x-axis.) If you get stuck, try graphing the equations.

y=x^2-25



y=x^2+16

PLEASE HELP!!
