Polynomial and Rational Functions
If represents rate change original position function , then question asks identify correct interpretation given statement concerning expressions involving these functions.
Q evaluates average speed period starting ending points being considered
Q determines acceleration rate corresponding interval
Q measures instantaneous velocity object moving according P's path time T
Q calculates total distance traveled until moment T
Given the function , where a and b are constants, if the rate of change of is always positive, what can we say about the values of a and b?
The value of a must be less than or equal to zero, while b must be greater than zero.
The value of a must be less than or equal to zero, while b can be either positive or negative.
Both a and b must be positive.
The value of a must be greater than or equal to zero, while b can be negative.
Which of the following is a possible zero for a polynomial function?
An integer value where the graph crosses the x-axis.
A fraction greater than one where the graph touches but does not cross the x-axis.
A complex number that causes shifts in the vertical asymptote.
A negative decimal point where the graph has a local minimum.
If represents a vertically stretched quadratic function, what is true about its vertex compared to that of ?
It has not shifted but is reflected over the y-axis due to multiplication by -2.
It is shifted right by five and up by seven with reflection across x-axis due to multiplication by -2.
It is shifted left by five and down by seven with no reflection across any axis.
It is shifted right by five and down seven with reflection across y-axis due to multiplication of x-coordinates by -1/5.
If the leading coefficient of a polynomial function is doubled, how does this affect the end behavior of the graph?
The graph becomes steeper and approaches infinity or negative infinity more rapidly.
There will be a vertical stretch by a factor of two in the whole graph.
The x-intercepts of the graph are shifted horizontally.
The end behavior does not change.
