Suppose that the dollar value v(t) of a certain car that is t years old is given by the following exponential function. v (t) = 32,000(1.28)' Find the initial value of the car. s0 Does the function represent growth or decay? growth decay By what percent does the value of the car change each year? Х 5 ?



Answer :

By using percentages ,that value of the car increases each year by 28%.

What in math is a percentage?

In essence, percentages are fractions with a denominator of 100. We place the percent symbol (%) beside a number to indicate that it is a percentage.

            For instance, you would have received a 75% on the examination if you correctly answered 75 out of 100 questions (75/100).

The initial value of the car at time 0 = 32000(1.28)0

= $32000

From the given function, we can see that the function represents a growth in the value of the car, as the time passes.

The value of the car increases by a fixed percentage each year. We can see that the value will increase each year by the factor of 1.28. Hence, we can say that value of the car increases each year by 28%.
