Find the equation of the tangent line to the curve when x has the given value. F(x) = -2- x2; x=-1 Oy = .x - 1 O y = 2x - 1 O y = -2x +1 O y = -2x D Question 13 Suppose an object moves along the y-axis so that its location is y = f(x) = x2 + x at time x (y is in meters and x is in seconds). Find the instantaneous velocity at x = 4 seconds. O 10 m/s 0 9 m/s O 8 m/s 0 9m
