7.2 Graphing Polynomial Functions Relative maximum Relative minimum
Making a table to graph Graph the function f(x) = -x3 - 4x2 + 5 The graph will cross the x axis 3 or less times since the degree is 3.
Making a table to graph Graph the function f(x) = -x3 - 4x2 + 5 The graph crosses the x axis 3 times
Find the area where the function equals zero f(x) = x4 – x3 - 4x2 + 1 Make a table
Find the area where the function equals zero f(x) = x4 – x3 - 4x2 + 1 Make a table
Find the area where the function equals zero f(x) = x4 – x3 - 4x2 + 1 Make a table Where are the zeros? between -2 and -1 - 1and 0 0 and 1 2 and 3
What are the Relative Maximum or Relative Minimum It is an area where the highest or lowest points happen. We make a table. Graph the points and look for the highest and lowest points.
What are the Relative Maximum or Relative Minimum Make the table for f(x) = x3 – 4x2 + 5
What are the Relative Maximum or Relative Minimum Make the table for f(x) = x3 – 4x2 + 5 between -1 and 1 Relative Max between 2 and 3 Relative Min.
Graph the function Between what numbers are the zeros of the function?
Graph the function Between what numbers are the zeros of the function? Between -7 and -6 -4 and -3 3 and 4
