Short Answer

Find the value of f2,f1,f0,f5,fx2,f1x for the function fx=xx.

The value of function are

f-2=1,f-1=1,f0=undefined,f5=1,fx2=1,f1x=1.

See the step by step solution

Step by Step Solution

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

From the given function,

fx=|x|x ....1

Evaluate the value of function at x=2,1,0 gives,

role="math" localid="1644518088722" f2=|2|2 ....Substitute x=2 in 1 =1f1=|1|1 ....Substitute x=1 in 1 =1 f0=00 ....Substitute x=0 in 1 Which is undefined

Step 2. Evaluate f5,fx2,f1x for the given function.

Similarly, evaluate the value of function (1) at x=5,x2,1x gives,

role="math" localid="1644518425397" f5=|5|5 ....Substitute x=5 in 1 =1 fx2=|x2|x2 ....Substitute x=x2 in 1 =1f1x=1x1x ....Substitute x=1x in 1 =1

Step 3. Description of steps.

From the obtained values,

f-2=1,f-1=1,f0=undefined,f5=1,fx2=1,f1x=1.
