The average price of a movie ticket in 1990 was $4.25. Since then the price has increased by approximately 3.6% each year. Write an exponential function to find the price of a ticket in 2022.

The function is

A(2022)=$13.45

Step-by-step explanation:

-Let A denote the ticket price.

The general equation for an exponential function is given as:

Where:

Given the rate of growth is 3.6% per year and the initial ticket price was $4.25:

#First find the time interval:

we substitute our parameter values to estimate the ticket price in 2022:

Hence, the ticket price in 2020 is $13.45

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
