The number of customers regularly visiting a new restaurant has grown exponentially at a rate of 12% per year since the restaurant opened. The function F(x) = 50 * (1.12) ^ x represents the total number of regular customers x years after its opening . Approximately how many customers does the restaurant have now , 3 years later ?

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

probably the last option

step-by-step explanation:

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
