Consider f(x) = 3x² - x + 2, with Dom(f) = R. (a) Compute f(-2), f(), ƒ(2). (b) Draw a Cartesian plane, and put the three points you computed on the plane. (c) Join the 3 points in the simplest possible way, to obtain an approximation of the graph of f. (d) Given a generic number a ER, compute the values f(a), ƒ(–a), ƒ(a+1), 2ƒ(a), ƒ(2a), ƒ(a²), [ƒ(a)]². Consider f(x) = 3x² - x + 2, with Dom(f) = R. (a) Compute f(-2), f(), ƒ(2).
