Question

??(??) = −2?os(?) + 2 a. Graph the function over the interval [-2pi, 2pi]. Use values of quadrantal angles. Set up the axes with appropriate scales. Be neat please! b. Give the domain and range of the function c. Find the y-intercept of the graph. d. For what numbers x, on the interval [-pi, pi] is the graph of F(x) decreasing? e. What is the absolute maximum value of F(x) over the interval [0, 2pi]? f. Will the absolute maximum value of F(x) be different if we work over the whole domain of F(x)? Explain. g. Give all values of x on the interval [-2pi, 2pi] where F(x) = 0. h. Give an x < -2pi for which F(x) = 0. i. Give all values of x on the interval [-2pi, 2pi] where F(x) = 2. j. Give an x > 2pi for which F(x) = 2.
