Answer:

Third option: The graph moves left 18 units.

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If f(x)+k, the function is shifted up "k" units.

If f(x)-k, the function is shifted down "k" units.

If f(x+k), the function is shifted left "k" units.

If f(x-k), the function is shifted right "k" units.

In this case, we can observe that graph of y = (x - 9)^2 is changed to y = (x + 9)^2

Since:

 -9+18=9

We can conclude that the function y = (x - 9)^2 is shifted left 18 units to get the function y = (x + 9)^2.

D) If C.P. - Rs 100, S.P. Rs 80, then loss percent​
AfilCa [17]

Step-by-step explanation:

Selling price = Rs.80

Cost price = Rs.100

here, CP > SP

Now...

Loss ( L ) = CP - SP

= RS.100 - 80

= Rs.20

Now...

loss \: percent \:  =  \frac{loss}{CP}  \times 100%

=  \frac{2000}{100}  \\

= 20 %
