What is the exponential regression equation that fits these data?

The exponential regression equation that fits the data values is:

Step-by-step explanation:

We are given a table of data value as:

          x               y

         -4            0.025

         -3            0.075

         -2             0.25

         -1              0.70

          0               3

          1                8

          2              20    

          3              60

          4             160

Hence, on plotting these data points we observe that the line of best fit is a exponential curve and the equation that will best fit these data points is:

              Hence, option: C is the correct answer.

thus, the first answer choice, y = sec x, is the correct one
