Answer:
-2x+3
Step-by-step explanation:
Gradient is change in y over change in x
=2
and then
+3 because that's where it cuts the Y axis
What is the exponential regression equation for the data set x 3,4,7,11,12,16,19 y .3,.5,.9,1.2,1.7,1.7,1.9

Answer:
The exponential regression equation for the data set is;
Step-by-step explanation:
Exponential regression can easily be carried out in Ms. Excel. The first step is to enter the data in any two adjacent columns with the headers x and y in order to differentiate the response from the predictor variable.
The next step is to highlight the data, click the insert ribbon and choose the scatter-plot feature. This step will create an x, y scatter-plot for the data. The next step we click on the Add-Chart Element feature and add an exponential trend line to the scatter-plot while ensuring the Display Equation on chart is checked.
Ms. Excel provides the following exponential regression equation that models the data;
