The table shows the pay d (in dollars) as a function of the number of hours worked h. 1.) Complete the table of values and graph using the equation: Hours (h)14710 Dollars earned (d) 2.) Thinking of the graph of this function, should you connect the dots? Why or why not? 4.) Would it be reasonable to expect 40 hours to have $280 earned? Why or why not? 3.) How much money was made after working 4 hours? Express your answer in function notation.
WordYour GuessDefinitionExample Domain Range Max Value Min Value Zero/s Y-intercept The y-values that can be plugged into the function The point(s) where the graph crosses the x-axis (x-intercept) The point(s) where the graph crosses the y-axis The x-values that can be plugged into the function The highest point on the graph (in a particular interval) The lowest point on the graph (in a particular interval)
WordYour GuessDefinitionExample X-intercept Interval of Increase Interval of Decrease End Behavior Parent Function The interval where a graph is increasing (like climbing a hill) The interval where a graph is decreasing (like going down a hill) The direction the end of the graph is pointing. The head and tail of a graph. The basic functions used as building blocks for more complicated functions. The point(s) where the graph crosses the x-axis (zero)
Parent Graphs Thoughts on Parenthood….. Your children need your presence more than your presents. ~Jesse Jackson Parents often talk about the younger generation as if they didn't have anything to do with it. ~Haim Ginott What’s this have to do with math??????
How do we determine the domain of a function (by looking at it’s graph)? What is a max value? What is a y-intercept? How do you find it? What is a zero? How do you find it? How about the range? What is a min value?
