Using algebraic techniques answer the following questions about the following quadratic function. Show ALL your work. f(x)=3x+x-3 1. What is the axis of symmetry? 2. What is the vertex of the parabola? 3. What is the domain of the function? 4. What is the range of the function? 5. What is the y-intercept? 6. What are the x-intercepts (aka zeros)? (You may round these to two decimal places to help you graph them.) Using an ENTIRE PAGE of graph paper, carefully graph the function. Be sure to mark the scale on the x and y axes. This should be a nice, big, full-page graph. You may use Desmos to help but the graph needs to be hand drawn. Label the vertex, axis of symmetry and intercepts on your graph.
