please help me I will reward!
Which of the following exponential functions goes through the points (1, 20) and (2, 80)?
f(x) = 5(4)−x
f(x) = 4(5)−x
f(x) = 5(4)x
f(x) = 4(5)x

Best ResponseYou've already chosen the best response.0none of these are exponential the way they are written but i will assume that they should be written such as for a. f(x)= 5^((4)x)

Best ResponseYou've already chosen the best response.0ya sure just so you know you can solve the question you are given by plugging in 1 or 2 for x and making sure that you get either y=20 for x=1 or y=80 for x=2

Best ResponseYou've already chosen the best response.0The value of a rare painting has increased each year since it was found at a garage sale. The value of the painting is modeled by the function f(x) = 799(1.03)x. What does the 799 represent? What will the painting be worth after 5 years? Round your answer to the nearest dollar. 799 represents the value of the painting when it was found; the painting will be worth $926 after 5 years 799 represents the increase in the value of the painting; the painting will be worth $103 after 5 years 799 represents the value of the painting when it was found; the painting will be worth $804 after 5 years 799 represents the total value of the painting; the painting will be worth $926 after 5 years

Best ResponseYou've already chosen the best response.0well I believe the way the 799(1.03)(x) has an exponent but I dont know where so I cant solve it
