Quadratics and Trig

Answer the questions below about the quadratic function. f(x)=2x² - 4x Does the function have a minimum or maximum value? What is the function's minimum or maximum value? Where does the minimum or maximum value occur? x=

The graph of a quadratic function with vertex (1, -3) is shown in the figure below. Find the domain and the range.

Use a graphing calculator to find all the real zeros of the quadratic function. f(x)=2x² - 6x-1 Round to the nearest hundredth.

Solve the equation by graphing. -x²-12x-32=0 First, graph the associated parabola by plotting the vertex and four additional points, two on each side of the vertex. Then, use the graph to give the solution(s) to the equation. If there is more than one solution, separate them with commas.
