Functions

Many students seemed to enjoy our new game called "Guess My Rule." We used the game to learn more about functions and about how to write function rules. Some of the students who had their hands up often were Keegan B, Mary O, Bryan C, Chris G, Dana S, Kraig R, Mack R, Peter F, Tyler H, Riley S, Jesse S, Danielle S, Ashley M, Scott D, Keegan D, Quin W, Brett C, Kyle J, Marissa N, Molly D, Mike M, Ashlyn M, Steve S, Jordan T, Martin H, Tyrone C, Jeff B, Chad W, Levi G, and Sierra K. I'm sure that I accidentally left out many names because so many students were eager to participate. We will continue to play the game throughout the year!

Check out this picture. Can you find the function rule for this one?????? Post the function rule as a comment!

Remember to look for patterns!!! Can you figure out if x=0 what does y= ? Knowing the value of that number is helpful in writing the function rule. If that y value does not equal 0, what operations may be in the function rule?

I've figured it out!

f(x) = -x + 25

Mrs. Morey said...

Nice work, Alen! That was a tough one.

Can anyone come up with another way to write the rule for this function?

t-pach said...

i still think it was impossible alen is just cool like that XD

Unknown said...

I know another way to write it.

f(x) = -1x + (-25)

Unknown said...

I correct myself. What I meant to say
is

f(x) = -1x + 25

Wow! I'm impressed with the work I see here! I sure need some updating on my math knowledge;I used to be so proud of myself. Now, I feel stupid-yuch to me!
