Quadratic Basics
A quadratic equation always has this as an exponent.
What is 2?
This is where the quadratic equation intersects the y-axis.
What is y-intercept?
If the parent function is y = x2, and the graph changes to y = x2 + 4, the new graph will move in which direction?
What is up?
What is parabola?
What is vertex?
If the parent function is y = x2, and the graph changes to y = x2 - 6, the new graph will move in which direction? (remember to identify the number of units too)
What is 6 units down?
Complete the standard form: ax2 + bx + ...?
What is c?
This is the name of the line that cuts the quadratic equation exactly in half.
What is axis of symmetry?
What type of symbol would you add to the equation y = x2, to flip it over the x-axis?
What is a negative symbol/sign?
A quadratic function always has a second difference of this number?
What is 2?
The roots/zeros of a quadratic function are never on which axis?
What is the y-axis?
If the parent function is y = x2, and the graph changes to y = x2 + 5, the new graph will move in which direction? (remember to identify the number of units too)
What is up 5 units?
What are the 3 types of quadratic forms we've covered?
What are vertex, standard, and factored form?
A vertical line is drawn through the vertex of the function, what is this line called?
What is axis of symmetry?
If a parent function is y = x2 and the new graph changes to y = (x + 1)2, which direction and how many units is the new graph moving?
What is one unit to the left?
