Exponential Function
Sign in to play this song with your class.
Sign inDEFINITION:
a function whose value is a constant raised to the power of the argument, especially the function where the constant is e.
HOW TO:
Graph the function y = 2x + 1. This will look kinda like the function y = 2x, but each y-value will be 1 bigger than in that function
Everyday Use: Null
Lyrics
Excuse me class (exponential high)
May I have your attention please
Excuse me
May I have your attention please (and bases low, bases low)
I raise the base to the power that I wanted (that I wanted)
Now they can’t tell me nothing (why?)
Cause it’s the topic of discussion (yes sir)
And that’s the exponential, exponential function (let’s go)
First is an equation for you scholars
A times B raised to the X power
See we ain’t living off potential
If you ever check our growth, you will see that its exponential
If you’re looking for a pattern, you will see it never adds up
I mean it’s a different bill when it stacks up
Make sure you’re really getting this
All of our friend should always be multiplicative (yes)
And even if you settle on a graph
We’ll never line up you should do the math
Yea, we’ll start of slow
But we’ll shoot up right off go
So, you should check us out
I mean it graph goes sky high
You can even wave it bye-bye
So, there’s no need assumptions
Cause you know now what’s exponential functions (let’s go)
I raise the base to the power that I wanted (that I wanted)
Now they can’t tell me nothing (why)
Cause it’s the topic of discussion (yes sir)
And that’s the exponential, exponential function (let’s go)
I raise the base to the power that I wanted (that I wanted)
Now they can’t tell me nothing (why?)
Cause it’s the topic of discussion (yes sir)
And that’s the exponential, exponential function (let’s go)
Standards
- CCSS.MATH.CONTENT.HSF.LE.A.1.A — Prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.
- CCSS.MATH.CONTENT.HSF.LE.A.1.C — Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.
- CCSS.MATH.CONTENT.HSF.LE.A.1 — Distinguish between situations that can be modeled with linear functions and with exponential functions.
- CCSS.MATH.CONTENT.HSF.LE.A.1.B — Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.
- CCSS.MATH.CONTENT.HSF.LE.A.2 — Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).
- CCSS.MATH.CONTENT.HSF.LE.A.3 — Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function.
- CCSS.MATH.CONTENT.HSF.LE.B.5 — Interpret the parameters in a linear or exponential function in terms of a context.
- CCSS.MATH.CONTENT.HSF.LE.A.4 — For exponential models, express as a logarithm the solution to abct = d where a, c, and d are numbers and the base b is 2, 10, or e; evaluate the logarithm using technology.
