CHAPTER 6- TRANSFORMATION OF GRAPHS

Answers

3) let y = 7 - 3x 

    put y =0 ,then x = 2.3                            (2.3 , 0)

    put x = 0 , then y = 7                            (0,7)

    put x = 7 , then y = -14                          (7, -14)

    Now draw the graph of y = 7- 3x using these points. 

Then to sketch  |7-3x|   reflect the part below the x- axis on the x-axis. 

b) range for the domain 0 ≤x ≤7 is 0  ⩽y⩽14

   Note:         💃Range    → y limit

                💆 Domain → x limit

      

Note: Questions 3 and 4 are the same functions. The only difference in question 3 is , limit of x is given.

    

4) 

The upper part is the required region.

  So, the range is 0 to ∞
