Line tangent to a function
Nettet24. des. 2024 · Find the tangent line to the curve y = x3 at x = 0. Solution: Use formula ( [eqn:tangentline]) with a = 0 and f(x) = x3. Then f(a) = f(0) = 03 = 0. The derivative of f(x) = x3 is f ′ (x) = 3x2, so f ′ (a) = f ′ (0) = 3(0)2 = 0. Hence, the equation of the tangent line is y − 0 = 0(x − 0), which is y = 0. Nettet5. jul. 2024 · The tangent line passes through the point (2,4) and hence substituting in the above equation we get: 4 = 4(2)+c c = -4; The final equation of the tangent line is y = 4x-4; 3. f(x) = x^3+2x+1. This function is shown below, along with its tangent lines at x=0, x=2 and x=-2. Below are the steps to derive an equation of the tangent line at x=0.
