Exponential function?

Step-by-step explanation:

For example, have a look at the y-axis values of R.

y=0.1/0.01=10

y=1/0.1=10

y=10/1=10

y=100/10=10

Here, the ratio of y-axis values of R is constant.

But, the ratio of x-xis values is not constant.

i.e. x = -1/-2 = 1/2

     x = 0/-1 = 0

     x = 1/0 = ∞

     x=2/1=2

Here, the ratio of x-axis values is not constant.

But, as we know that for a function to be exponential, the ratio of both x-axis and y-axis values should remain constant.

Therefore, NOT A SINGLE OPTION IS CORRECT.

In other words, NO A SINGLE OPTION IS CORRECT WHICH MAY SHOW the graph being exponential.

40% off the regular price is the correct answer.
