simply chart it out. f(x) g(x) f'(x) g'(x) 2| -3 4 -2 7 then plug them into the equations. A. (5)-3 - 4(4) -15 - 16 = -31 B. (-3)4 = -12 C. -3/4 D. 4/1-3 = 4/-2 = -2

well the chart didn show up right but when x = 2 then f(x) = -3 g(x) = 4 f'(x) = -2 g'(x) = 7 then plug them into the equations. A. (5)-3 - 4(4) -15 - 16 = -31 B. (-3)4 = -12 C. -3/4 D. 4/1-3 = 4/-2 = -2

f'(x) = secxtanx then use the product rule and figure out the derivative of that: f''(x) = tanxsecxtanx + secx sec^2x and then it becomes tan^2x + sec^3x. then you plug in pi/4 which is 45 degrees. it is (1)(1.41) + 2.83 and the answer is 4.24
