Find functions f(x) and g(x) so the given function can be expressed as h(x) = f(8(x)). 22. h (x ) = (x+ 2) 23. h (x) =- 4 (x + 2)? 24. h (x) =3+Vx-2 25. Given the function f (x) = 2x2 + 4 and g(x) =2, find f+ g, f- g, fg and f/g and determine each of their domains.26. The function A(d) gives the pain level on a scale of 0-10 experienced by a patient with d milligrams of a pain reduction drug in their system. The milligrams of drug in the patient's system after t minutes is modeled by m(1) . To determine when the patient will be at a pain level of 4, you would need to: a. Evaluate A(m(4)) b. Evaluate m( A(4)) c. Solve A(m(t)=4 d. Solve m( A(d))=4 27. The radius r, in inches, of a spherical balloon is related to the volume, V, by r(V) = = 3V Air is pumped into the balloon, so the volume after i seconds is given by V (t) =10+20t. a. Find the composite function r(V (:)) b. Find the radius after 20 seconds28. A rain drop hitting a lake makes a circular ripple. If the radius, in inches, grows as a function of time in minutes according to r(t) = 25vt + 2 , find the area of the ripple as a function of time. Find the area of the ripple at t = 2 minutes.18.
