Evaluate the function at the given value of x. Round your result to three decimal places.
Function ................................................................................. Value
1. f (x) = 0.9x ............................................................................ x = 1.4
2. f (x) = 4.7x ............................................................................ x = −π
3. f (x) = 3x ............................................................................ ... x = 2/5
4. f (x) = (2/3)5x ........................................................................ x = 3/10
5. f (x) = 5000(2x) ...................................................................... x = −1.5
6. f (x) = 200(1.2)12x .................................................................... x = 24
