Using Transformations to Graph Quadratic Functions Flashcards
1
Q
How do you use a table to graph Quadratic Functions?
A
You solve with the table until you have enough points to see both sides of the graph curve.
2
Q
What is a Quadratic Function?
A
A function in the form f(x)=a(x-h)^2+k (a =/= 0)
3
Q
How do you translate a Quadratic Function up or down?
A
You add + or - k at the end of the equation.
4
Q
How do you translate a Quadratic Function to the left or right?
A
You make h a positive or negative number (negative goes right and positive goes left).
5
Q
What happens when the x is negative in a Quadratic Translation?
A
The parabola flips over to be upside-down.
6
