Ascatter plot was created to show the increase in value of a baseball card over time. the equation of the line of best fit is shown below, where x represents the number of years after 1987, and y represents the value of the baseball card in dollars. which of the following is predicted by the equation of the line of best fit? a. the value of the baseball card would be $36.52 in 2017. b. the value of the baseball card would be $18.30 in 2017. c. the value of the baseball card would be $27.24 in 2022. d. the value of the baseball card would be $21.35 in 2022.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
