the polynomial 0.0058x^4 -0.0041x^3+0.14x+1.97 gives the predicted sales volume of a company, in millions of items, where x is the number of years from now. determine the predicted sales 11 years from now. round your answer to two decimals.

Solution

f(x) = 0.0058x^4 -0.0041x^3+0.14x+1.97

find the value of f(x) when x=11

f(11) = 84.9178 - 5.4571 +1.54 +1.97

=82.9707

= 82.97
