Unformatted text preview: But, if f ( x ) = 3 x 31 x , we know that f ( x ) = 9 x 2 + 1 x 2 , f (1) = 2 ; in particular, g (2) = 1 and f (1) = 10 . Consequently, g (2) = 1 f (1) = 1 10 . keywords: 007 (part 1 of 1) 10 points Find the value of lim x →∞ µ 5 e x + ex 2 e x5 ex ¶ . 1. limit = 1 5 2. limit = 5 3. limit =4 7 4. limit =1 5 correct 5. limit =5 6. limit = 4 7 Explanation: Multiplying top and bottom by e x we see that 5 e x + ex 2 e x5 ex = 5 e 2 x + 1 2 e 2 x5 . On the other hand, lim x →∞ e ax = 0...
