Write your original function definition in pencil, namely
\ =\ |x|\ +\ 20)
For problem (a), erase the 
and write 0 in its place. Then do the indicated arithmetic.
Do the same thing for all of the other problems, replacing the with the value inside the parentheses for that particular problem, simplifying the expression as much as possible in each case.
By the way, if you need to create absolute value bars in the future, find the "backslash" key, generally right above the "Enter" key on your keyboard. Hold "Shift" and press the "backslash" to get the "pipe" symbol: |

Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
absolute value of a number is the number if it is positive and it is the positive number if the number is negative
a. 20
b.22
c.22
d.x+20
e.-(x+20), since this is how an absolute value can be made negative
f. x+30
g. 6x+20
h. |x+h|+20. The shape of this graph will be transformed -h units horizontally and 20 units vertically.
