PLS HELP Simplify the function f(x) =
3x
(81)
4
Then determine the key aspects of the function.
The initial value is
The simplified base is
The domain is
The range is

Step-by-step explanation:

This follows the form

where a is the initial value and b is the base with the exponent.  Using that information, we can see that the initial value in our function is 1/3. Simplifying the base will take some work. Let's first rewrite this is a radical:

Now let's break up 81 into its factors. 81 is 9*9 which is 3*3*3*3.  Therefore,

We will use that as a simplification:

 which simplifies to

Rewriting that as an exponent looks like this:

which simplifies to

That's the answer for the second part.  The whole exponential equation now is

The domain for an exponential function is all real numbers and the range is

y > 0

78.59 is the mean

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
