Solutions

Chapter 2.1, Problem 28E
To determine

To evaluate f(2),f(1),f(0),f(1),f(2) valuesby using the piecewise function f(x)={5,                 if  x22x3,         if   x>2  

Expert Solution

Answer to Problem 28E

The required functions of the values are f(3)=f(0)=f(2)=5,f(3)=3,f(5)=7

Explanation of Solution

Given information:consider the piecewise function f(x)={5,                 if  x22x3,         if   x>2  

Calculation:

First find the values of f(3),f(0),f(2)

Since the values of x=3<2,x=0<2,x=2

From the above piecewise function,to be taken as

  f(x)=5

  f(3)=5

  f(0)=5

  f(2)=5

Find the values of f(3),f(5)

Since the values of x=3>2,x=5>2. and x=5>0

  f(x)=2x3

  f(3)=2(3)3f(3)=3

  f(5)=2(5)3f(5)=7

Thus, the required function of the values f(3)=f(0)=f(2)=5,f(3)=3,f(5)=7
