A graph or part of a graph which looks like an upside-down bowl or part of an upside-down bowl.
Back
Concave up
Front
A graph or part of a graph which looks like a right-side up bowl or part of an right-side up bowl.
Back
Average Rate of Change
Front
The change in the value of a quantity divided by the elapsed time. For a function, this is the change in the y-value divided by the change in the x-value for two distinct points on the graph.
Back
Cusp
Front
A sharp point on a curve, that is not differentiable.
Back
Power Rule
Front
The formula for finding the derivative of a power of a variable.
Back
Decreasing Function
Front
A function with a graph that moves downward as it is followed from left to right. For example, any line with a negative slope.
Back
Critical Number
Front
The x-value of a critical point.
Back
Discontinuity
Front
A point at which the graph of a relation or function is not connected.
Back
Tangent Line
Front
A line that touches a curve at a point without crossing over. Formally, it is a line which intersects a differentiable curve at a point where the slope of the curve equals the slope of the line.
Back
Constant Term
Front
The term in a simplified algebraic expression or equation which contains no variable(s).
Back
Continuously Differentiable Function
Front
A function which has a derivative that is itself a continuous function.
Back
IVT
Front
A theorem verifying that the graph of a continuous function is connected.
Back
Relative Maximum
Front
Where the function has a horizontal tangent line and the derivative graph goes from positive to negative.
Back
Second Derivative
Front
The derivative of a derivative. Usually written f"(x) or y".
Back
Instantaneous Rate of Change
Front
The rate of change at a particular moment. Same as the value of the derivative at a particular point.
Back
Derivative
Front
A function which gives the slope of a curve; that is, the slope of the line tangent to a function.
Back
Limit
Front
The value that a function or expression approaches as the domain variable(s) approach a specific value.
Back
Calculus
Front
The branch of mathematics dealing with limits, derivatives, definite integrals, indefinite integrals, and power series.
Back
Cartesian Form
Front
A function (or relation) written using (x, y) or (x, y, z) coordinates.
Back
Extremum
Front
An extreme value of a function. In other words, the minima and maxima of a function
Back
Increasing Function
Front
A function with a graph that goes up as it is followed from left to right.
Back
Curve
Front
A word used to indicate any path, whether actually curved or straight, closed or open.
Back
Relative Minimum
Front
Where the function has a horizontal tangent line and the derivative graph goes from negative to positive.
Back
Asymptote
Front
A line or curve that the graph of a relation approaches more and more closely the further the graph is followed.
Back
Bounded Function
Front
A function with a range that is a bounded set. The range must have both an upper bound and a lower bound.
Back
Critical Point
Front
A point (x, y) on the graph of a function at which the derivative is either 0 or undefined.
Back
Infinity
Front
A "number" which indicates a quantity, size, or magnitude that is larger than any real number.
Back
Continuous Function
Front
A function with a connected graph.
Back
Normal Line
Front
Perpendicular to the tangent line
Back
First derivative test
Front
A method for determining whether an inflection point is a minimum, maximum, or neither.
