QveST [7]

Answer:

<em>The correct option is:  D)  S(a) = 2.00a + 100.00; shift 50 units up</em>

Step-by-step explanation:

The rent for an apartment is represented by  R(a) = 2.00a + 50.00

Now, the rent increases by $50.00 when the apartment is furnished. So, the rent of a furnished apartment will be:  (2.00a+50.00+50.00) = (2.00a+100.00) dollar

Thus the new function will be:   S(a)= 2.00a+100.00

<u>As the output of the original function is increased by 50.00, so the graph of the original function will shift 50 units upward</u>.
