Lesson Goals

You will be able to "Evaluate" a quadratic function by changing inputs to evaluate outputs.

Lesson Video:

(NOTE: Example 1 Question B should have a final answer of -8. f(-2) = -8)

Notes:

Let's bring this back to a table... where we started at the very beginning with our Arithmetic Sequences.

His first example in the video is used here:

You need to be able to plug in inputs to discover their outputs as you've done before.

What we need to consider moving forward is are there limitations to the table?

Can there be a negative x?
Is the function continuous or like with most things a discrete function. Can X be any number? Can it be 1.576839?

THE TABLE IS A GREAT PLACE TO EVALUATE THIS FUNCTION!

What you may notice:

Do you see the pattern?
