FINDING EQUATION OF TANGENT LINE WITH …

WebFind the slope of the tangent line to the graph of the function f (x) = x^3 f (x) = x3 at the point (2, 8) (2,8). Solution Since (x_0, y_0) = (2, 8) (x0,y0) = (2,8), using the slope of the tangent line formula \displaystyle m_ {\tan} =\lim_ {h \to 0} \dfrac {f (x_0 + h) - f (x_0)} {h} mtan = h→0lim hf (x0 + h) − f (x0) we get WebFor finding values of x where the tangent line to the graph is horizontal using the equation 2x^2 + 3x - 1 would you simply find the derivative of the equation and set that answer to 0? And if so, the answer would be -3/4? • ( 2 votes) kubleeka 6 years ago That's correct. The statement "the derivative of 2x^2+3X-1 is 0" implies "x= -3/4". book a cab edinburgh

Web1 Determine the point at which the graph of the function has a horizontal tangent line. f ( x) = 5 x 2 x 2 + 1 I figured out the derivative, 10 ( x 2 + 1) 2, but I'm not sure where to go after this in order to find the horizontal tangent line. Any help? edit: fixed the denominator, that was a typo. Apologies calculus functions derivatives Share WebThey're saying the tangent line to the graph of function f at this point passes through the point seven comma six. So if it's the tangent line to the graph at that point, it must go … god is unwilling that any should perish
