The delta x and delta y (dx and dy) are the changes in x and in y. When you take the derivative you are provided with a ratio (rise over run) of these changes.
Take f(x)=3x^2 + 2x
Derivative: (dy/dx)=6x + 2
From this, you can solve for dx and dy algebraically.

How do you find x and y intercepts?
if you are looking at a graph the y intercept is when the graph crosses the y axis and the x intercept is when the graph crosses the x axis. if you have a formula... plug zero in for x to find the y intercept, and plug zero in for y to find the x intercept
Find the coordinates of a second point on the graph of a function f if the given point is on the graph and the function is even?
If the point (x,y) is on the graph of the even function y = f(x) then so is (-x,y)
How do you find points on a parabola to graph them?
Select a set of x values and find the value of y or f(x) - depending on how the parabola is defined. These are the values that you need to graph.
How do you graph sin squared x?
The graph of the function y = (sin x)^2 has the same amplitude 1, and the same period 2pi, as the graph of the function y = sin x. The only difference between them is that the part of the graph of y = sin x which is below the x-axis is reflected above x axis. In order to graph the function y = (sin x)^2, we need to find the values of (x, y) for the five key points, where 0 ≤ x ≤ 2pi. Values of (x, y) on y = (sin x)^2: x = 0, y = 0 x = pi/2, y = 1 x = pi, y = 0 x = 3pi/2, y = 1 x = 2pi, y = 0 Plot these five key points and connect them with a smooth curve and graph one complete cycle of the given function.
How do you determine in a math problem if the graph has an x or y axis?
A graph has both an x and y axis.
How do you find x and y intercepts?
if you are looking at a graph the y intercept is when the graph crosses the y axis and the x intercept is when the graph crosses the x axis. if you have a formula... plug zero in for x to find the y intercept, and plug zero in for y to find the x intercept
How do you find the gradient of velocity time graph?
to calculate the area of any straight line graph or part of a graph, you need to select two points. for example (x1,y1) and (x2,y2). once you have selected the points you put then into the equation m=delta y/delta x (change in y divided by the change in x) which is easier as m=(y2-y1)/(x2-x1) and m = the gradient
What describes how to translate the graph y x to obtain the graph of y x - 6?
To translate the graph y = x to the graph of y = x - 6, shift the graph of y = x down 6 units.
Find the coordinates of a second point on the graph of a function f if the given point is on the graph and the function is even?
If the point (x,y) is on the graph of the even function y = f(x) then so is (-x,y)
Find the y-intercept of the graph y equals sin x?
It is zero.
How do you graph y x 2?
It is a line. There are many ways to graph it using intercepts etc. But, you can pick some x points, plug them in your equation, and find the corresponding y point, The graph those (x,y) values
How do you find the x-intercept and the y-intercept of a graph?
X axis is across and Y axis is down
What is a pair of numbers to determine the point on a graph?
A pair of numbers are usually (x,y) if u want to determine a point on a graph. Find the value for both x and y and then plot them on a graph
How do you find x and y?
More information is needed to determine x and y. Do you have a point on a graph? Are you given a formula?
What is Slope of an equation?
When an equation is in slope-intercept form (y = mx + b), the slope is the variable m, where y is the the y-coordinate, x is the x-coordinate, and b is the y-intercept (where the line crosses the vertical axis). Slope is calculated as rise over run, or delta y over delta x. For example, you have a line on a graph and you need to know the slope. Find two points from that line and write down its coordinates--say, (2,6) and (4,8). The change in y (delta y, rise) is 2, because 8 - 6=2. The change in x (delta x, run) is 2, because 4 - 2=2. Note: make sure that when subtracting the x and y coordinates, that you do them in order. For example, don't go 8-6 and then 2-4. Since slope is delta y over delta x, the slope of the line is 2/2, or 1.
What are the the x and y intercepts for the graph of 5x-2y equals 20?
To find x, sub 0 in for y. To find y, sub 0 in for x.y= -10, x= 4
Where would the solutions of 5x-6y30 lie on a graph?
the purpose of equations like that is to find the x and y values. if you graph this equation 5x - 6y = 30 then you need to find the place where the like will cross the x-axis and y-axis. first find the equation equal to y y = (5/6)x - 5 x = 6 y = -5
