Afunction has a domain of {1, 3, 5, 7} and a range of {2, 4, 6}. which set of ordered pairs represents this function? a.{(1, 2), (3, 4), (5, 6), (7, 2)} b.{(1, 2), (3, 6), (5, 4), (5, 2)} c.{(1, 2), (3, 2), (5, 2), (7, 2)} d.{(1, 4), (3, 4), (5, 6), (7, 6)}

Consider the function f left parenthesis x right parenthesis equals 4 x squared minus 3 x minus 1f(x)=4x2−3x−1 and complete parts (a) through (c). (a) find f left parenthesis a plus h right parenthesis f(a+h); (b) find startfraction f left parenthesis a plus h right parenthesis minus f left parenthesis a right parenthesis over h endfraction f(a+h)−f(a) h; (c) find the instantaneous rate of change of f when aequals=77.
