The 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.

well one of the key principals to this site is to help understanding and not give answers...

campbell_st · Answer

if x is time in years.... this growth model is just an application of the compound interest formula. 

so if you subsitute x = 0    that with give the initial value of the painting... 

remember anything to the power zero is 1

campbell_st · Answer

the 2nd part of the question tells you 5 years later so x =5

make the substitution and calculate the value... 

$$f(5) = 799 \times (1.03)^5$$

that's all that is needed
