Stack #31910
| Question | Answer |
|---|---|
| find the function? | vertical line test |
| graph function? | table of values |
| linear function | y=mx+b |
| is it linear? | has to be in y=mx+b format |
| find slope? | y2-y1/x2-x1 |
| domain? | x |
| range? | y |
| 1 to 1? | horizantal line test |
| end behavior? | walk the x-axis to on neg or pos sides to see which way graph curves (infinity or neg infinity). |
| decreasing? | (blank) |
| what values restricted from domain? | what value of x makes y=0? |
| translated? | left, right, up, down |
| matrix demensions? | row x column |
| det [ ]? | criss-cross and subtract from eachother |
| axis of symmetry? | (blank) |
| invers function? | switch x and y, then solve for y |
| min/max? | (blank) |
| matrix form? (when changing to a matrix) | AX=B, so A-1B=x |
| multiplicative inverse? | det=0 (no inverse). det /=0 (yes inverse) |
| poly functions w/ table? | subtract right from left until all answers are the same |
| find determinant? | b2-4ac |
| # real roots? | >0=2 real; =0=1 real; <0=2 imaginary |
| zeros are the same as | answers |
| (a-bi)^2? | (a-b)(a-b) |
| i^2 = | - |
| (i)/(i) | multiply by the conjugate; |
| rational zeros | P/Q |
| explicit | gets nth term - arithmetic |
| recursive | a1 = ___; r (a (down)n-1) |
| when multiply in sequence, use | geometric |
| when adding in sequence, use | arithmatic |
| a1 is the | first term in a sequence |
| d or r are the | numbers multiplied/added in between sequence |
