To find the slope derivative of a function at a specified value of x perform the following steps. Direct link to this answer. If having slopes in this a positive of point one that would be very flat something down here we might have a slope closer to point one.
If the given curve is y f x yfx y f x we evaluate d y d x dfrac dy dx d x d y or f x fx f x and substitute the value of x x x to find the slope.
The slope of the curve y x2 3 at the x value of 1 is 2. Tutorial video showing how Excel can be used to find the slope of a line. For each interval calculate the change in y and divide by the change in x. Find the slope of the curve y x 2 at the point 24 using a numerical method.
