The value of function are


See the step by step solution

Step by Step Solution

Step 1. Evaluate f−2,f0,f12 for the given function.

From the given function,

fx=2|x1| ....1

Evaluate the value of function at x=2,0,12 gives,

role="math" localid="1644516780178" f2=2|21| ....Substitute x=2 in 1 =2|3| =6 f0=2|01| ....Substitute x=0 in 1 =2 ....|1|=1f12=2121 ....Substitute x=12 in 1 =212 =1

Step 2. Evaluate f2,fx+1,fx2+2 for the given function.

Similarly, evaluate the value of function (1) at x=2,x+1,x2+2 gives,

role="math" localid="1644517286232" f2=2|21| ....Substitute x=2 in 1 =2 fx+1=2|x+11| ....Substitute x=x+1 in 1 =2xfx2+2=2x2+21 ....Substitute x=x2+2 in 1 =2x2+1

Step 3. Description of steps.

From the obtained values,
