To find the y-intercept of a function, set x to 0 and solve for y. How do you find the intercepts of a function? The intercepts of a function may be found graphically by examining where the line crosses the x- and y-axes. If the line does not cross the x- or y-axes, however...
I have a polynomial function and I would like to find all the "x" values for a "y" value. For example I have tried to plot this function: x=[0:0.05:23] f=@(x) 152.094827571469-206.917405701416*x+188.571689289441*(x.^2)-93.85238987*(x.^3)+25.7783269818991*(x.^4)-4.346577795030...
In the simplest case, there is a set of points {(x 1, y 1), …, (x n, y n)} in the plane (image space) that lie on a straight line, parameterized by y = k 0 x + d 0, where k 0 is the slope and d 0 is the intercept of the line. A line passing through...

Finding X-axis Intercept So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses...
Hello, I was wondering if there is an easy way to find the slope and intercept of a line using MATLAB, like how it is so easy with Excel where you just plot the data and add a trendline, so then it will tell you the slope and intercept. Here is my code ThemeCopy tau = [15, ...
Without going into too much unnecessary detail. I wish to fit a straight line to the data in order to find the x values when the fitted lines intercept with the blue lines (Wi*=0.002). An example is shown below: I have tried using the polyfit command ...
of electrons in a β−-group with end point energy Tmax by the simple expression N = a2Tmax2I(Z, Tmax), where a is the y-intercept in the Fermi-Kurie plot, I(Z,Tmax)=∫0Tmaxf(Z,T)h(T)dT, where f is the Fermi function and h(T)=(T+1)(1−T/Tmax)2[T(T+2)]−1...
Other possibilities are to locate it in the formula in slope intercept form, find the derivative of a curve and plug in an x value to find the slope, or to use a slope function on a spreadsheet. How do you find the slope given two points? Solve for slope using the change in y ...
