A) i believe it is jupiter because 4.39 is the largest number and its to 10^8
b) smallest is mercury because 1.54 is the smallest and it’s only 10^7
The only increasing function is the last option:

<h3>
Which function is increasing?</h3>
Here we only need to see that, is as x increases also do f(x). Then the function will be increasing.
The cases for exponential functions is actually more trivial than that.
- If the base is between zero and 1, then the function is decreasing.
- If the base is larger than 1, then the function is increasing.
In the given options there is only one function with a base larger than 1, which is the last option:

That is the correct option.
