In order to evaluate the function at the given values of x, let's use these values of x in the function and calculate its value.
So, for f(5.24), we have x = 5.24:

Rounding to one decimal place, we have f(5.24) = 149.0.
Now, for f(-8.36), we have:

Rounding to one decimal place, we have f(-8.36) = 444.4.
