Find f'(x) for f(x) = 2x + 3x - 1. Be sure to use f'(x) = lim BH to get credit. or f'(x) = lim A-0 f(x+h)-f(x) h f(b)-f(x) b-I Find the limit lim 1+ H4 2 a (x - )]. 2 x tan x + ln 18. (BONUS, 5 pts) Find f'(x) for f(x)=x. Be sure to use f'(x) = lim f(b) = f(x) bir to get credit. or f'(x) = lim h0 f(a+h)-f(x) h 16. (7 pts) Find f'(x) for f(x) f(x+h)-f(x) h f'(x) = lim CC 4x I- 5 to get credit. = f(b)-f(x) or Be sure to use f'(x) = lim: (4(x+h) bx bIH Use the e- & definition to prove that lim(3x + 7) = 22. x15 Use the e-6 definition to prove that lim (x - 1) = 63. 1-8
