This is for my calculus class, these are review questions for an exam that we are preparing for. Any help would be appreciated!

3. Given the values listed below, evaluate f_34[8f(x) 4g(x)]dx. ff f(x)dx = 33 gimme = 5 ff 90061;: = 9 f2 mm = 14 4. The number of albums sold per day by an artist 1' days after the release of that album is given by the function f(x) = 3000 + 3x $63". How many albums were sold in the first 10 days after release? Round your answer to one decimal place. [Note: You need to at least write out what the antiderivative of this function is, but y0u may use technology to plug in the values.]
