Answer:
<h2> The skateboard has a total cost of $90.10</h2>Step-by-step explanation:
Givens
- The skateboard costs $85.
- The sales tax is 6%.
The total cost of the skateboard would be $85 plus the sales tax, like the following expression shows
Therefore, the skateboard has a total cost of $90.10, which includes sales tax.
The inverse of this function would be f(x) = .
You can find the value of any inverse function by switching the f(x) and the x value. Then you can solve for the new f(x) value. The end result will be your new inverse function. The step-by-step process is below.
f(x) = - 1 ----> Switch f(x) and x
x = - 1 ----> Add 1 to both sides
x + 1 = -----> Take the logarithm of both sides in order to get the f(x) out of the exponent
Log(x + 1) = f(x)Log3 ----> Now divide both sides by Log3
= f(x) ----> And switch the order for formatting purposes.
f(x) =
And that would be your new inverse function.
