1. For each function, state the slope of a line that is perpendicular to it. a) y=2x +9 b) y=-5x - 3 2. Simplify. Express answers using positive exponents. a) (x2)-3 2x3- x-+ 3x 3. Determine the value of y when x = 4. a) y = 6u2 - 1, u = Vx b ) y = - 5 13, 4=9-2x 4. Identify the type of function (polynomial, rational, logarithmic, etc.) represented by each of the following. a) f(x) =5x3+2x-4 b) y = sin x () g(x) = -2x2+7x+1 d) f (x) = vxx e) b(x) = 5*
