U. s. internet advertising revenue grew at the rate of r(t) = 0.82t + 1.14 (0 ≤ t ≤ 4) billion dollars/year between 2002 (t = 0) and 2006 (t = 4). the advertising revenue in 2002 was $5.9 billion.† (a) find an expression f(t) giving the advertising revenue in year t.

Where C is a constant, now using the initial condition we got:

And solving for C we got:

And the function desired for the advertising revenue would be given by:

With f the amount in billions and the the years since 2002 to 2006.

Explanation:

For this case we have the following function who represent the revenue grew rate:

And we want to calculate the Advertising revenue so we need to integrate the function r(t) and we can use the inidital condition t=0 , f(2)= 5.9 billion.

If we integrate the function we got:

Where C is a constant, now using the initial condition we got:

And solving for C we got:

And the function desired for the advertising revenue would be given by:

With f the amount in billions and the the years since 2002 to 2006.
