On the grid below is shown the parabola y = -2x- and the line y = -2x. (a) Sketch the following graphs on the grid below. i) the graph of a concave down parabola which has the same shape as y = -2x2 but has vertex at (-3, -1). Scroll below to the grid. On the menu above the graph, select the parabola icon. Then click on the vertex and another point. Once you click on the grid, you may drag the point to where you would like. You need not click exactly on an integer point on the grid, but try to click as close as possible to the point (-3, -1). ii) the graph of a line parallel to y = -2x that passes through the point (-3, -1). Note: On the menu above the graph, select the line icon. Then click on two points. (b) Report the formula of the parabola in part a.i. You may use vertex form, factored form, or standard form. TIP: Click on the Plot icon (p) next to the answer box to see the graph. y= (c) Report the formula of the line in part a.ii. TIP: Click on the Plot icon (p) next to the answer box to see the graph. Use this grid for your sketches requested in part (a): 5 4 3 -5 -4 1-3 -2 -1 1 2 3 14 5 -1 -2 -3 -4 -5
