Tell whether or not each table contains data that can be modeled by an exponential function. Provide an equation to show the relationship between x and y for the sets of data that are exponential. a. X 1 2 3 3 6 12 24 Exponential? Yes or No b. X 1 y 4 8 Exponential? Yes or No C. 1 2 y 108 36 12 4 Exponential? Yes or No

Tell whether a linear model or a quadratic model is appropriate for the data. If linear, tell whether the slope should be positive or negative. If quadratic, decide whether the leading coefficient of x should be positive or negative.

L7Q8.Find the relationship between the two variables in the given data.

Find a graph or bar chart that represents a real situation where you could use a linear or exponential equation to model the data. Identify the type of function that is being modeled and why you believe it to be this type. Estimate the equation for the function.
