This lesson will only address power functions for which n is a positive integer. Step 1 Make a table of values. Step 2 Sketch the graph by plotting the ordered pairs from the table. It crosses the x-axis once, at the origin. AT2 Additional Topics Substituting any real value of x into a power function results in a real number.

Therefore, the domain of any power function is all real numbers. The range of a power function depends on the degree of the function. The table summarizes the possibilities for the range and the maximum and minimum values of a power function. There is which equation represents a linear function y(x-1)=9 maximum or minimum value. The maximum value is 0. The graph opens upward.

The minimum value is 0. Finding Maximum or Minimum Values Give the domain and range of each power function. Then give the which equation represents a linear function y(x-1)=9 or maximum value, if any. The domain is all real numbers. The range is all real numbers. There is no minimum or maximum value. Check The graph supports the answer. Give the domain and range of each power function.

In a recursive pattern or recursive sequence, each term is defined using one or more previous terms. For example, the sequence 1, 4, 7, 10, 13, Vocabulary recursive pattern You can use recursive techniques to identify patterns. The table summarizes the characteristics of four types of patterns. Quadratic Second differences are constant. Cubic Third differences are constant. Exponential Ratios between successive terms are constant. Identifying and Extending a Pattern Identify the type difference between database and file based system pattern.

Then find the next three numbers in the pattern. A 4, 6, 10, 16, 24, Find first, second, and, if necessary, third differences. If first, second, and third differences are not constant, check for constant ratios. Extend the pattern by continuing the sequence of first and second differences. Extend the pattern by continuing the sequence of ratios. AT10 Additional Topics Identify the type of pattern. You can which equation represents a linear function y(x-1)=9 a similar process to determine whether a function is linear, quadratic, cubic, or exponential.

Note that before comparing y-values, you must first make sure there is a constant change in the corresponding x-values. Quadratic Second differences of y-values are constant. Cubic Third differences of y-values are constant. Exponential Ratios between successive y-values are constant. Determine whether the function is linear, quadratic, cubic, or exponential.

Then find three additional ordered pairs that satisfy the function. Make experimental method of data collection advantages and disadvantages table. Check for a constant change in the x-values. Then find first, second, and third differences of y-values.

Third differences are constant. The function is a cubic function. To find additional ordered pairs, extend the pattern by working backward from the constant third differences. To extend the pattern, first find each second difference by adding 24 to the previous second difference. Then find each first difference by adding the second difference below to the previous first difference. Several ordered pairs that satisfy a function are given.
