Draw the graph of, y = x^2 – 2x – 4
1)First, let's create a table of values for x and y. For this example, let's pick values of x ranging from -2 to +4.2) We will then input our values of x into the equation, and get a corresponding value of y. We will add this to the table. E.g, for when x = -1 y = (-1)^2 - 2(-1) - 4 = 1 + 2 - 4 = -1 and so on.3) On a graph of y against x, we will plot our corresponding values, with a small cross/dot.4) We'll join up our points on the graph free-hand to form a curve (don't use ruler).
