## anonymous one year ago 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.

799 represents the value of the painting when it was found; the painting will be worth \$926 after 5 years

Pretty sure

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

7. campbell_st

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

8. campbell_st

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

can u help me with one more @CBARREDO1

For f(x) = 0.01(2)x, find the average rate of change from x = 12 to x = 15.

Sure
