Document Summary
Instructions: solve all problems in the space provided. Sketch an accurate graph of each of the following functions. Find the domain, range, intercept(s) (if any), and asymptote(s) (if any) of each function. domain: y-intercept (if any): (b) y=21x+41-2. ; asymptote(s) (if any): domain: y-intercept (if any): ; asymptote(s) (if any): (over) ( c ) y = 1 - log3 x domain: Sketch an accurate graph of y = -3cos(nx + n) over two periods along the nonnegative x- axis. Find the amplitude, phase shift, and clearly label on your graph all intercepts. amplitude: Sketch an accurate graph of each of the following equations. If the graph is a parabola, find its vertex, focus, directrix, and axis of symmetry. If it is an ellipse, find its center, foci, and the length of its major and minor axes. (a) 2 x + 6 x + 9 y = o.
