1. a) Complete the square to put the following function in vertex form for graphing a parabola. Explain how the formula x= is used to determine the vertex. 2a b) State the vertex, the domain, the range, and the axis of symmetry. c) On what intervals is the function is increasing, decreasing, or constant and write its maximum or minimum value. d) Find the real zeros of the quadratic function using the quadratic formula. How is a zero different from an x-intercept? How are they related? e) Graph the parabola on the axes provided. f(x) =-2x +4x+1 2. Find the equation of the line containing the point (-2,5) and that is perpendicular to the line 2x+4y =-1.
