Step-by-step explanation:
- If the ratio between the x-axis and y-axis values remain constant. Then the graph would be an exponential function.
- In other words, if there is constant change in x values, as well as y values, then the graph would be an exponential function.
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.
