Problem 2 Graphing: Graph the quadratic equation at desmos.com/calculator using the technique from Problem 2.
Rewrite the equation in standard form, replace 0 with y, and graph it.
Use the settings menu (⚙️ icon) to convert the equation to a table of values.
Modify x-values in the table to identify the solution(s) within the table. Look for inputs that lead to outputs of 0.
Zoom and pan your graph to establish an appropriate viewing window.
Capture a screenshot that includes your graph and the table.
Upload or paste your screenshot to the canvas.
Use the Formative canvas tools to add the following annotations to your screenshot:
1 - Identify where to find the solution(s) in the table and on the parabola.
2 - Use highly-visible colors that contrast with the background.
4x^{2}-14x+7=4-x

Problem 3 Graphing:
Graph the quadratic equation below at desmos.com. Remember to substitute y for 0.
Zoom and pan your graph to establish an appropriate viewing window.
Click on the vertex and x-intercepts to label them.
With all 3 labels showing, take a screenshot of your graph.
Upload or paste your screenshot to the canvas.
Use the canvas tools and a contrasting color to circle the x-intercepts. Remember that their x-values represent the solutions of the original equation.
