| Term | Definition |
|---|---|
| Point symmetry | A figure that has this symmetry can be rotated 180 degrees about the point and appears unchanged. |
| Symmetry with respect to the origin | F(-x) =- f(x) |
| Symmetry with respect to the x-axis | Tested by substituting (a,b) and (a, -b) into the equation produces equivalent equations. |
| Symmetry with respect to the y- axis | Tested by substituting (a,b) and ( -a,b) into the equation produces equivalent equations |
| Symmetry with respect to the y=x line | Tested by substituting (a,b) and (b,a) into the equation produces equivalent equations |
| Symmetry with respect to the Y =-x | Tested by substituting (a,b) and (-b,-a) into the equation produces equivalent equations |
| Even function | Functions whose graphs are symmetric with the y-axis. Tested substituting ( -a,b) |
| Odd function | Functions whose graphs are symmetric with respect to the origin. F(-x) = f( -x). Can rotate the graph of the function by 180 degrees and it appears unchanged. |
| Parent graph | The basic graph that is transformed to create other members in a family of graphs |
| Reflection of y = -f(x) | Reflected over the x-axis |
| Reflection of y = f(-x) | Reflected over the y- axis |
| Translation of y = f(x) + c | Translates the graph up c units |
| Translation of y = f(x) - c | Translates the graph down c units |
| Translation of y = f( x + c) | Translates the graph c units left |
| Translation of y = f(x - c) | Translates the graph c units right |
| Change to the parent graph y=f(x), c >0 Y = c f(x), c >1 | Expands the graph vertically resulting in a more narrow graph |
| Change to the parent graph. y = f(x), c > 0 Y = c f(x), 0<c<1 | Compresses the graph vertically resulting in a wider graph |
| Change to the parent graph y=f(x), c>0 Y = f( cx), c>1 | Compresses the graph horizontally resulting in a more narrow graph |
| Change to the parent graph y = f(cx), 0<c<1 | Expands the graph horizontally resulting in a wider graph |
| Inverse relations | Only if one relation contains the elements (a,b) and the other relation contains the elements (b,a) |
| Horizontal line test | A test used to determine if the inverse of a relation is a function. If every horizontal line intersects the graph in at most one point, then the inverse is a function. |
| Asymptote | It is a line the function approaches, but never crosses. |
| End Behavior | The behavior of a function as x goes to positive infinite and as x goes to negative infinite. Written like x-> + infinite, y-> x-> - infinite, y-> |
| Maximum | This is a critical point where the curve changes from an increasing curve to a decreasing curve. |
| Minimum | This is a critical point where the curve changes from a decreasing curve to an increasing curve. |
| Inverse | It is shown when a function is rotated about the line y = x. the equation can be found by switching the x's and y'x and solving for y. |
| Critical point | It is the part of the graph where the nature of the graph changes; this includes minimums, maximums, and points of inflection. |
| Absolute minimum | Is a minimum that is the smallest y-value of the entire function. |
| Absolute maximum | Is the maximum that has the largest y-value of the entire function. |
| Discontinuous | When a function has a break, hole, or is undefined at any point. |
| Point of Inflection | When a function has a critical point where the graph changes its curvature form concave down to concave up or vice versa. |
| Continuous | A function is said to be this at point(x1,y1) if it id defined at that point and passes through the point without a break. |
| Monotonicity | A function is this on an interval I if and only the function is increasing on I or decreasing on I. |
| Relative maximum or minimum | A point that represents the maximum or minimum for a certain interval. |
| Jump discontinuity | The graph of f(x) stops and then begins again with an open circle at a different range value for a given value of the domain. |
| Infinite Discontinuity | As the graph of f(x) approaches a given value of x, f(x) becomes increasingly large without bound. |
