Free functions intercepts calculator - find functions axes intercepts step-by-step
Article SummaryX. To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y. If you don't know the slope, calculate it by dividing the rise of the line by the run.
The calculator will find the x- and y-intercepts of the given function, expression or equation. Show Instructions. In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. In general, you can skip parentheses, but be very careful: e^3x is `e^3x`, and e^(3x) is `e^(3x)`.
How Do You Use X- and Y-Intercepts To Graph a Line In Standard Form? To find the x-intercept of a given linear equation, simply remove the 'y' and solve for 'x'. To find the y-intercept, remove the 'x' and solve for 'y'. In this tutorial, you'll see how to find the x-intercept and the y-intercept for a given linear equation. Check it out!
The y-intercept is the place where the line crosses the y-axis and the x-intercept where the line crosses the x-axis. For simple problems, it is easy to find the x-intercept by looking at a graph. You can find the exact point of the intercept by solving algebraically using the equation of the line.
Using a graphing calculator is a fast and effective way to identify the X and Y intercepts of a function. Using the built-in tools allows you to find the intercepts without doing the algebra. Enter the equation. Press the "Y=" button on the calculator. Clear out any existing equations.
Since the y-intercept marks the point where x =0, all that you have to do is substitute 0 in for x in the parabola's equation. Interactive Demonstration of the intercepts Explore the relationship between the x and y intercepts of a parabola and its graph by changing the values of a,b and c of the parabola plotter below
