A Daily Equation

A Daily Equation 👉 Middle school math, decoded for parents.
👉 You’re not bad at math—you’re just still mad at long division.

Same input.
Very different outputs.
Weather is not a function 😳

01/24/2026

Linear graphs have a constant beat.
Straight lines. Same moves. Same rhythm.
No surprises — just disco. 🪩

It’s a function… but what kind? 👀

Straight line?
Same rate of change → linear

Curvy situation?
Changing rate of change → nonlinear

Before formulas.
Before overthinking.
👉 Trust your eyeballs.

Function first.
Then we ask: linear or nonlinear?

01/20/2026

The numbers can change — the function rules don’t.

We can math tomorrow.

Festive fades. Glitter is forever. ✨

Before, we just called this the rule.
Now we give the rule a name: f(x).

f(x) just means ‘do the function to x.’
Same cooking. Fancier menu.

Not all relations are functions.
Can you find the impasta? 🍝

(Check the x-values.)

The vertical line test is just another way to check the same rule.

If a vertical line hits the graph more than once,
one input has more than one output — and it’s not a function.

01/13/2026

Functions aren’t fancy — they’re just picky. 😄

Each input only gets one output.
