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!!
