HOW TO BE OK at FUNCTIONS - Intro to functions: slope, rise, run, y-intercept, domain, range
(Some devices aren't playing all the audio tracks, so I have gone back and underlayed some additional midi that will at least give it a substantial framework for any device. For best results listen with headphones or on a computer)
LYRICS:
Alright stop – collaborate and listen
Mac is back with a brand new lesson
Something grabs a hold of me tightly
Grows like a function daily and nightly
Will it ever stop? Yo – I don’t know
‘cause to infinity it can go
To find the extreme determine y-min or maximum
I flow like Miyagi telling you to “wax-it-on”
Mac he’s a mathematical poet
I’m talkin ‘bout functions – ‘case you didn’t know it
DOMAIN – X – is a faithful hun
Never paired with more than one
RANGE - makes you wonder “Y”
He’s a player and that ain’t so fly
If it is a function YO – I’ll prove it:
Lay your pencil vertical and then move it.
NICE NICE FUNCTIONS y = mx + b
Now that we’re talkin ‘bout functions
With the bass kicked in and the party is jumpin
80 or more when you learn with this melody
Anything less on the test is a felony
y-INTERCEPT is the b yo check this:
Where the graph crosses the y-axis
To determine y just make x zero
That’s one step to bein a function hero
SLOPE – equals rise over run
m is the slope – it’s dope –that’s fun!
RISE – is the change in y
Subtract points 2 and 1, that’s right
RUN – through the horizontal plane
It’s the change in X – do you hear what I’m sayin’?
If there was a problem – YO, we’ll solve it
Check out the book while teacher revolves it.
