28. Reasoning Suppose that a function pairs elements from set A with elements from set B. A function is called onto if it pairs every element in B with at least one element in A. For each type of polynomial function, and for each set B, determine whether the function is always, sometimes, or never onto. a. linear; B= all real numbers b. quadratic; B= all real numbers c. quadratic; B= all real numbers greater than or equal to 4 !!
