1. Templates & Reset

Reset RAM (Pre-Exam):
[2nd] [MEM] → [7] → [1] → [2].

Pretty Fractions:
[ALPHA] [Y=] → [1].

Decimal to Frac:
[MATH] → [1].

2. Graphing Essentials

Find Zeros:
[2nd] [TRACE] → [2]. Select bounds.

Find Intersect:
[2nd] [TRACE] → [5]. Hit [ENTER] 3x.

Find Vertex (Max/Min):
[2nd] [TRACE] → [3:min] or [4:max].

Reset View: [ZOOM] → [6].

3. Regressions (Fit)

Enter Lists: [STAT] → [1]. (L1, L2).

Linear (ax+b): [STAT] → [CALC] → [4].

Exponential: [STAT] → [CALC] → [0:ExpReg].

Missing "r"? [2nd] [0] → scroll to DiagnosticOn → [ENTER] [ENTER].

4. 1-Var Stats

Results: [STAT] → [CALC] → [1].

- \(\bar{x}\): Mean
- \(\sigma x\): Standard Deviation
- Med: Median
- \(Q_1\)/\(Q_3\): Quartiles

5. Equation Solver

Numeric Solver: [MATH] → [B:Solver]. Type eq as \(0 = \text{expression}\) to find \(x\). Best for checking complex equations!

6. MC Testing Trick

The "TEST" Menu: Use this to check if a choice is correct without solving.

Store value for X: 5 → [STO] → [X].
Type equation: \(2x+5\)
Select symbol: [2nd] [MATH] → [1: =].
Finish eq: \(15\). Hit [ENTER].

1 = TRUE | 0 = FALSE

The table [2nd][GRAPH] is your best friend for factoring. If your factored expression doesn't have the same Y-values as the original, you made a mistake!
