Then find the domains of f/lg and g/f. ★******* ******************************************************** Composition of Functions Definition of Composition of Two Functions- The composition of the function of f with the function g is: (fo g) (x) =f(g (x)). The domain of (fo g) is the set of all x in the domain of g such that g (x) is in the domain of f. For instance, iff (x)= x² and g (x) = x+1, the composition of f with g is: f(g (x)) = (x+1) Abe (Н.W) If f(x) = 4 - x² & g(x) = Vx then find (fog)(), (gof)(x) x+8 If f(x) = 3x - 8 & g(x) = then find (fog)(x).

- The gravitational force exerted by the planet Earth on a unit mass at a distance r from the center of the planet is GM, GM if r R F(r) = where M is the mass of the earth, R is the radius, and G is the gravitational constant. Is F a continuous function of r? Explain your answer.arrow_forwardConsider the function f with the following properties: f is continuous everywhere except at r = -1 • f(-3) = 1, f(-2) = 0, f(0) = -2 • lim f(x) = +oo, lim f(r) = -0o, lim f(r) = 2, lim [f(r) - (-1- 1)] = 0 %3D I+-1 f" Conclusions f' |(-0,-3) -3 Intervals (-3,-2) -2 (-2,-1) -1 DNE DNE (-1,0) + (0,+x) (a) Give the equations of all the asymptotes of the graph of f.

(c) Sketch the graph of f with emphasis on concavity. Label all asymptotes with their equations and important points with their coordinates.arrow_forwardQuestion: Explain a method that could be used to find the absolute maximum and minimum values of a continuous function fon a closed interval [a, b].
