This theorem states that every polynomial equation of degree n with complex number coefficients has n roots, or solutions, in the complex numbers
What is the Fundamental Theorem of Algebra?
A number’s distance from zero on the number line.
What is absolute value?
A function which is defined by two or more equations, each valid on its own interval
What is a piecewise function?
the point where the three medians of a triangle intersect
What is centroid?
A part of a population selected to represent the entire population
What is sample?
The distance along the arc of a circle. Part of the circumference.
What is arc length?
A derived solution to an equation that is invalid in the original equation
What is an extraneous solution?
a point at which a function is undefined
What is a discontinuity?
the point where the three angle bisectors of a triangle intersect
What is incenter?
The group of individuals you want to study in order to answer your research question
What is a population?
The time it takes for one complete cycle of a trigonometric function
What is the period?
a function that can be written in the form
f(x)= P(x)/Q(x) where P and Q are polynomials in x and Q is not the zero polynomial.
What is a rational function?
functions that "reverse" each other
What are inverse functions?
the point where the three perpendicular bisectors of the sides of a triangle intersect
What is circumcenter?
This type of sample is one in which every possible sample (of the same size) has an equal chance of being selected from the target population
What is a random sample?
The height from the midline (center line) to the maximum (peak) of a periodic graph. Half the distance from the minimum to the maximum values of the range.
What is the amplitude?
The values of the independent variable (x-values) that make the corresponding values of the function (f(x)-values) equal to zero.
What is are zeros (of a function)?
the inverse of an exponential function comprised of 3 parts: the base, the exponent, and the argument
What is a logarithm?
To draw a circle that passes through all of the vertices of a polygon.
What is circumscribe?
a study in which the researcher simply observes the subjects without interfering
What is observational study?
A line that intersects a circle at exactly one point
What is a tangent line?
This theorem states when a polynomial f is divided by (x-a), the remainder equals f(a).
What is the Remainder Theorem?
A horizontal axis that is used as the reference line about which the graph of a periodic function oscillates
What is a midline?
To draw (a figure) within another so that their boundaries touch
What is inscribe?
a statistic expressing the amount of random sampling error in the results of a survey
What is margin of error?
