Chapter 6 Flashcards
Turning point
Any point on the graph where the function changed direction
Constant function
A polynomial function with a degree of 0
Linear function
A polynomial function with a degree of 1
Quadratic function
A polynomial function with a degree of 2
Cubic function
A polynomial function with a degree of 3
Standard form for a linear function
y=ax+b
Standard form of a quadratic function
y=ax2+bx+c
Standard form for a cubic function
y=ax3+bx2+cx+d
Leading coefficient
The coefficient of the term with the greatest degree in a polynomial function in standard form.
Line of best fit
A straight line that best approximates the trend of a scatter plot
Regression function
A line or curve of best fit, developed by statistical analysis of data
Interpolate
The process used to estimate a value within the domain of a set of data, based on a trend
Extrapolate
The process used to estimate a value outside the domain of a set of data, based on a trend.
Curve of best fit
A curve that best approximates the trend of a scatter plot.
End behaviour
The description of the shape of the graph, from left to right , on the co-ordinate plane
