How do you graph a parabola?
y=x2+4x+1
How can you calculate a slope of graph?
Points: (x, y) and (x, y) Slope: y1-y2/x1-x2
What equation will make a heart on a coordinate graph?
x2+(y-x2/3)2=1
How do you accurately graph y -x2 8x 5 as a parabola?
There are two (main) ways to graph this parabola. The first is to simply substitute in values of x, find the corresponding y values and then plot those points and connect the points with a curve. The second way is to 'complete the square' so that we can find where the maximum or minimum occurs and the y-intercept and graph from those two points. This is the process described below. y = -x2 + 8x + 5 y = -(x2 - 8x) + 5 y = -(x2 - 8x + 16 - 16) + 5 y = -(x2 - 8x + 16) + 16 + 5 y = -(x-4)2 + 21 From this we can see that a maximum occurs at (4,21). To find the y-intercept, substitute in x=0, giving y=5. From these two points, we get a pretty good idea of what the graph looks like. If you want more accuracy, substitute in more values of x.
What is the effect on the graph of the equation y equals x2 plus 2 when it is changed to y equals x2 - 4?
the graph is moved down 6 units
