1. Given the function f (x) = , x , find: a) The average rate of change over the interval xE[3, 4]. (/1K) b) The instantaneous rate of change at x = 3. (/2K) c) The equation of the tangent line at x = 3. (/1A) d) The equation of the secant line between points x = 3 and x = 4. (/1A) e) Make a sketch of f(x) = - x and show the secant and tangent lines at their respective points. Please use a ruler. (/2K)
