1) Label your x-axis with the given interval 2) Enter function into Y1 and set xmin and xmax to interval, zoom 0 3) Create a table of values and plot those points on your graph 4) Find any relative extrema and plot on your graph 5) Determine the equation of any asymptotes and draw on your graph 6) Find any axes intercepts and plot on your graph 7) Draw the graph of the function, including all the points previously plotted 8) Make sure the y-axis reflects the range in the given interval 9) For trigonometric you need to determine period and amplitude Steps to Accurate Graphing
Accurate Graphing: Familiar Functions What are some functions whose graphs you already know? Polynomials Exponential Trigonometric Reciprocal/Rational
Step 1: Label you x-axis with the given interval
Step 2: Create a table of values(use the table in your calculator) x-7-6-5-4-3-2012 y
What would the period of this function be? What would be the amplitude?
Accurate Graphing: Unfamiliar Functions Graphing unfamiliar functions is done the same way as when graphing the functions whose shapes you know…..however, a calculator is necessary to determine the shape. Often if an unfamiliar function is a combination of two functions you know, then the new functions takes on some of the properties of the familiar functions
