Compute the average value of the following: a. f ( x ) = x 2 2 x + 3, 1 x 4 b. g ( t ) = cosh( t ), -ln(2) t ln(2) 11. The average value of x x f 1 ) ( = , 1 x t , is 0.1. What it t ? 12. A spring whose natural length is 2 feet requires a force of 100 pounds to keep it compressed to a length of 1.5 feet. How much work is required to compress the spring from a length of 1.5 feet to a length of 1 foot?...
