Find the slope of the tangent line to f(x) = - 4x / when x = - 2. The slope is (Simplify your answer. Type an integer or a fraction.)4 Find the slope of the tangent line to f(x) = = when x = 2. X The slope is (Simplify your answer. Type an integer or a fraction. )Find the equation of the tangent line to f(x) = - 4vx when x = 1. y (Simplify your answer. Use integers or fractions for any numbers in the expression. Do not factor.)By considering the graph of the function but not calculating any limits, give the value of f'(3) for the function f(x) = - 4x. f'(3) = (Type an integer or a fraction.)
