(Do this after you graph, so you can see the domain and the range easily.)Go to and graph your functions.If you are on a Mac: hold command + shift + 3 and drag over the graphIf you are on a Windows computer: Go to the snipping tool application and click on “New Snip”, drag over the graph, and click the purple save logo to save the capture.Go to wordGo to insert pictures and find your captureGo to format text wrapping in front of textUse the green circle to turn 90 degreesDrag it to the center of the top of the pageDo the same for other graphs, and put it on the bottom of the same page.PART A: LINEAR FUNCTION: f(x) = xReflect over the x-axis Domain?????????????Range f(x) = x(-∞, +∞)?????????(-∞, +∞)????????? ??g(x) = -x (-∞, +∞)?????????(-∞, +∞)????????? ??Graph f(x) and g(x) on the same coordinate grid.Reflect over the y-axis Domain?????????????Range f(x) = x(-∞, +∞)?????????(-∞, +∞)????????? ??g(x) = (-x) = -x(-∞, +∞)?????????(-∞, +∞)????????? ??Graph f(x) and g(x) on the same coordinate grid.Horizontal translation to the left 3 units Domain?????????????Range f(x) = x(-∞, +∞)?????????
