what are the x intercepts of the graph of the function y x 2 2x 15 On this algebra lesson you will learn how to find the x intercepts and y intercepts of a function linear and quadratic both algebraically and from a graph
An x intercept is where a graph crosses or at least touches the x axis that is the horizontal axis a y intercept is where the graph crosses or just touches the y axis that is the vertical axis So the graphical Graphing Using Intercepts Desmos For each problem find the x intercept and the y intercept and plot those points on the graph use and re use box 2 Then visualize sketch the graph Finally graph the

Learn how to find the x intercepts and y intercepts of a Linear Function and Quadratic Functions Solve for x and y intercepts and learn to plot them in the Cartesian Plane The y intercept is the point at which the graph crosses the y axis At this point the x coordinate is zero To determine the x intercept we set y equal to zero and solve for x
Y Intercept where the graph of an equation crosses the y axis To find the intercepts When you want the x intercepts x 0 Set y 0 then solve for x When you want the y intercepts 0 y Set x 0 then solve for y Definition of x and y intercepts The x intercept is the point where the graph of a line intersects the x axis The y intercept is the point where the graph of a line intersects

The general rule for finding the x intercept or intercepts of any function is to let y 0 and solve for x This may be somewhat easy or really difficult depending on the function To find the y axis intercept substitute x 0 into the equation and solve for y For example find the and y intercepts of 2y 3 12 To find the axis intercept first substitute y 0 into the equation When y 0 the
