This is how it should be done (correct answer to similar problem):

(1 point) Find an equation of the line that is tangent to the graph of y(x) = cos (2 + x ) at x = -4. Equation of the tangent line is } = 8sin(18)x + cos(18) + 32sin(18)(1 point) Find an equation of the line that is tangent to the graph of y(x) = sin(2 + x2) at x = 4 . Equation of the tangent line is y = -2(4)sin(2+(4)A2)
