I need help on these 5 calculus questions:

Question 6 (1 point) lim (1 - 6 = X-+ 00 X O - 6 Oe6 O 6 Oe - 6 OoQuestion 7 (1 point) The Mean Value Theorem states that if a function f(x) is continuous on [ab] and differentiable on (a,b), then there exists a point c in (a,b) such that the slope of the tangent line at c equals: O the average rate of change off between 0 and c O zero 0 the slope of the secant line between a and b 0 t) Question 8 (1 point) Suppose f(x) is differentiable on (-co, co), f(-3) = 4, and f' (x)
