Explanation of Solution

Given information:consider the function H(x)=|2x| .

Calculation:

Take any values of x and then make a table of values.

  xH(x)=|2x|1|2(1)|=22|2(2)|=40|2(0)|=01|2(1)|=22|2(2)|=4

Then, plot the points given by the table and join them by a smooth curve to obtain the graph H(x)=|2x| as shown below:
