Twenty years ago, mr. davis purchased his home for $160,000. since then, the value of the home has
increased about 5% per year. use an exponential function to find the value of the home today.

The value of home today is $ 424527.63

Solution:

Given that, Twenty years ago, Mr. Davis purchased his home for $160,000

Since then, the value of the home has  increased about 5% per year

To find: Exponential function to find the value of home today

The exponential growth function is given by:

Where, "y" is the worth after "t" years

"a" is the initial amount

"r" is the rate of interest per year

From given information,

a = 160000

t = 20 years

Substituting the values we get,

Thus the exponential function is found

Let us find the value

Thus the value of home today is $ 424527.63

answer: 1, 3 and 5 are correct

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
