a-umja-lca So the function has symmetry only about y-axis. It is called an even function. 2. y= f(x)=x}

\text { 20. } f(x)=|x-3|

The function C gives the number of bushels of corn produced on a tract of farmland that is treated with f pounds of nitrogen per acre. (a) Is it possible for C(95) to be negative? Explain. C(95) ---Select--- (b) What are the units on O bushels O pound per acre O bushels per pound/acre O pound per acre/bushel (c) Is it possible for be negative since the smallest amount of bushels of corn produced that can be produced is d=95 ? If = 95 dfff=95 ---Select--- be negative if the amount of corn produced is ---Select--- as additional pounds of nitrogen beyond 95 pounds per acre are applied. to be negative? Explain.
