The answer is no you cannot. Getting a car loan involves a contract. A 17 year old is still considered a minor in the eyes of the law. Because of this, a minor cannot enter into a binding contract.
The tangent at a given point on a curve is the straight line that just touches the curve at the given point. Leibniz defined this as being the straight line through two infinitesimally close points on the curve at that point, leading to the relationship between the slope of the tangent and the first derivative of the function (if both exist) at that point.
Both the graph of y = f(x) and the tangent line pass through the point, and the tangent line has the same gradient, 'm', as the function at that point. The normal line to function y = f(x) at the point (x1,y1) is the straight line that passes through the point making a 90 angle with the graph.The gradient of the normal line is -1/m, where 'm' is the gradient of the tangent line at the same point.'m' is the gradient at (x1,y1)). The equation of the normal line to y = f(x) at (x 1 ,y 1) is: The derivative of y = f(x) at (x 1 ,y 1) gives us the gradient 'm'. For example: Calculate the tangent and normal lines to the function: y = x 2, when x = 1. Solution: Part 1, tangent line.
