Q 1.Use the Rational Zero Theorem to list all possible rational zeros for the given function. f(x) = 6x4 + 5x3 - 4x2 + 4x - 5 2.Find a rational zero of the polynomial function and use it to ?nd all the zeros of the function. f(x) = x3 - 6x2 + 21x - 26 3.Find the inverse of the function and state its domain and range . {(4, 5), (-5, -4), (-1, 9), (1, -9)} 4. Use the graph of the given one-to-one function to sketch the graph of the inverse function. For convenience, the graph of y = x is also given. 5.The function f is one-to-one. Find its inverse.f(x) = (x + 2)3 - 8. 6.Decide whether or not the functions are inverses of each other.
