1. For each of these choices of function f and real numbers a and b, evaluate f at a and b. (a) f(x) = 3x + 7, a = 2, b = -1 x+2x+1 (b) f(x) = x+x-2 1 (c) f(x) = (d) f(x) = a=2, b = -1 a=6, x+62=6b = -5 1 a = 3,b=0 x+1 2. Find the domain of each function from problem 1. 3. For each function, determine whether the function is a polynomial function or not. If it is not, explain why not. If it is a polynomial function, determine the leading coefficient, the leading term, the degree, and the constant term. (a) f(x) = x + 17x - 3.175 (b) g(x) = r 3++1 (c) p(x) = 3x +7 (d) h(x) = (x+3) (2x 5)(2x 1)(x + 5) (e)k(x) = 3()
