For                 , find the domain value when the range is 17. Determine if the graph is a function.Not a FunctionFunction Given the inputs of {-3, 0, 3, 6}, name the domain and range of the function:(Separate numbers with commas, but no spaces)Domain: {               }Range: {                } For the function graphed below, determine the output value when the input value is 1. David measures how many inches his tomato plantgrows every week.What is the dependent variable?Inches the plant has grownThe number of weeks it has been growing What is the independent variable?Your math grade reflects the number of assignmentsyou have turned in.Math gradeAssignments turned in Cell phone bill, because it is the dependent variableCell phone bill, because it is the independent variableMinutes used, because it is the dependent variableMinutes used, because it is the independent variableThe minutes used each much determines your cell phone bill. If this relationship was graphed,which variable would be graphed on the x-axis?
