A tangent line is a line that touches the graph of a function in one point. Find the slope of the tangent line to the curve fx 2x 2 3x 4 passing through the point P-1 5. Dydx 2x 12.
Hence the slope of the tangent line at the given point is 1.
Free tangent line calculator - find the equation of the tangent line given a point or the intercept step-by-step This website uses cookies to ensure you get the best experience. Dydx 21 12 32. So when x is equal to two well the slope of the tangent line is the slope of this line. Y-y1 m x-x1 where m is our slope and x1 and y1 are the coordinates of a point.
