Introduction to Graphing equations:
Graph the following equation on your TI‐Nspire:y = x2 ‐ 3x + 2
1.) Press HOME and then 6: NEW DOCUMENTS (Do NOT Save) 2.) Add 2: GRAPHS & GEOMETRY3.) Enter in the equation after "f1(x) =" and then press ENTER.
What shape is the graph?
What values of x make y =0 in this equation? Explain.( Press MENU then WINDOW. Choose 3: Zoom‐In. Move your cursor to the middle of the U and press enter. Then press esc.)
Apply the transformation (x,y) → (x +5, y) to each point on the graph of y = x2 ‐3x + 2. Sketch the resulting graph on your graph paper. What is the equation of the new graph?
