Now we will find the distance between two points A and B on a curve defined by a function f(x) on a closed interval [a,b]. To find this distance we should use the formula s =The integral, between the lower limit, a, and the upper limit, b, of the integrand √(1 +[f'(x)]...
Complete a table of values. Use the solution points to sketch the graph of the equation. {eq}y = 2x^2 - x - 9 {/eq} Points on Graphs: Not all graphs are simple, like the graphs of linear functions being straight lines. In order to graph more c...
Draw a line through the focus perpendicular to the directrix. This line is the axis of the parabola. Find the point on the axis that is equidistant from the focus and the directrix of the parabola. This is the vertex of what will become a parabola. We call the distance from the focus ...
Identify the coordinates of the intersection between the graph and the y-axis. For this example, imagine an intersection at the point (0, 8). Identify one other point on the graph. For this example, imagine that another point on the graph has the coordinates (3, 2)....
