Get down with the lingo
AsymptoteAn imaginary line that the curve of an exponential function gets closer and closer to without ever actually hitting ('cause it's not nice to hit).
Cartesian Coordinate SystemThe flat grid we use to plot out functions. It has an x-axis, a y-axis, and a very big name.
DomainAll the values x can take in a function. It's like x is a little king, and the domain is, well, its domain.
Empty SetA set containing no elements. Move along folks; nothing to see here.
Exponential FunctionA function of the form y = abx + c. Their graphs form a nice, smooth curve.
FunctionA relation between sets of input and output where each input is related to one and only one output. The lobster model of mathematics.
GraphA diagram representing data or relationship(s) between variables.
InequalityA mathematical statement using the symbols <, >, ≤, ≥.
InterceptThe point where the graph of a function crosses the x-axis or y-axis.
Linear FunctionA two-variable equation that, when graphed on the coordinate plane, forms a straight line. It always sticks to the straight and narrow path.
Ordered PairTwo numbers written in a certain order; (a, b) is different from (b, a).
Quadratic FunctionA relation where the input (x) is related to the output (f(x)) by a quadratic equation: f(x) = ax2 + bx + c.
RangeThis is the set of all possible outputs of a function. It's generally the possible y-values. It has very little to do with the Lone Ranger or free range chickens.
RelationA set of ordered pairs. Like an infinite number of couples walking down an aisle at a wedding.
SetA collection of things, put inside curly braces. If you need your teeth straightened, your dentist will create a set of your teeth.
SlopeThe steepness of a line, calculated as rise over run; think skiing (the bunny slope is less steep than the triple black diamond).
VertexThe single maximum or minimum value of a parabola.
Vertical Line TestCan a vertical line pass through a graph twice? If yes, it's not a function. C'mon, this isn't a hard test to pass.
