|---|---|---|---|---|---|
| Leading Coefficent | The leading coefficient of a polynomial is the coefficient of the term of highest degree
🗑
|
||||
| Parent Function | Simplest function in a "family" of functions
🗑
|
||||
| Quadratic function | Polynomial function with a degree of 2
ex: x^2+7x=10
🗑
|
||||
| cubic function | function with a degree of 3
ex: x^3
🗑
|
||||
| square root function | function with a square root
/--------
\_/ x
🗑
|
||||
| cube root function | function with a cube root
3 /--------
\_/ x
🗑
|
||||
| standard form of quadratic function | f(x)=ax^2 +bx+c
🗑
|
||||
| Factored form of a quadratic function | f(x)=a(x-n)(x-m)
🗑
|
||||
| vertex form | completed quadratic square form
f(x)=a((x-h)^2)+k
🗑
|
||||
| roots of a polynomial function | Domain values for polynomial function that make the value of a polynomial function equal to zero when substituted for the variable
🗑
|
||||
| axis of symmetry | vertical line formed by the graph of the equation, when in standard form (f(x)=(ax^2)+bx+c), using the formula
x=(-b) % (2a) note %= divide
🗑
|
||||
| vertex | point where the graph and axis of symmetry intersect; it is considered a maximum or minimum, depending whether the leading coefficient is positive or negative
🗑
|
||||
| End Bahavior | opening of the function, when in standard form
(f(x)=(ax^2)+bx+c) opens up when a>0 and opens down when a<0
🗑
|
||||
| Quadratic formula | equation used when equation can not be factored
( (-b)(+or-) /------------------
\_/ (b^2) -4ac ) divided by (2a)
🗑
|
||||
| Discriminant | Used to describe how a graph looks ,^2-4ac
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
