Comment- Its really cool that the larger the number before the parenthesis, the wider the parabola opens up!

Question- Does the number before the parenthesis kind of act like the slope? Are there two sets of parenthesis because there are two parts of the quadratic function that branch from the vertex...or would that not make sense because they are technically the same rate of change on both sides from the vertex? <---- that may not make too much sense:)

Yes, the leading coefficient does kind of act like slope. However, parabolas do not have a constant rate of change like linear graphs do.

You do realise that the game is $56, right?

Hey I understand
Question; what I'f the number before the parentheses is like a realllllly long decimal then what would u do?

Mr. Bigsby

The longer the decimal does not matter, only if it a larger or smaller number.

1.315234523542354325 is still really close to 1, and 2 is still greater.

I'm having a lot of trouble with the classwork from today...just the graph on the back.

This is like what we did in class. On the homework, can you teach us how to find the Y of the vertex. It's still hard for me to find out

Mr. Bigsby

2/5/2016 05:03:01 am

Yes, we learned to plug in the X value into the equation.

Just wondering, how long is pi supposed to go?

Mr. Bigsby

2/5/2016 12:41:48 pm

Pi never ends. There are mathematicians right now doing long division trying to find the next digit in pi.
