The coefficient of b (that is, 2) divides into 2b and also into 8, so it is a factor (a value that is multiplied by another value to produce a term in an expression)

What is the inverse of the function??

Firlakuza [10]

$$\begin{matrix}
y=ln(x+3)\\
e^y=x+3\\
e^y-3=x\\
swap ~x~and~y\\
 \huge\underline{y=e^x-3}}
 \end{matrix}$
$

To get the inverse of any function f(x) [ just make sure that it passes the horizontal line test] follow the steps:

- Solve for x, i.e separate x in one side and the other terms in the other side, included f(x).

- Swap x and f(x).

- The result is the inverse of the original function $f^{-1}(x)$ .

-------------------------

Apply that on your function
$$\begin{matrix}
y=ln(x+3)\\
e^y=x+3\\
e^y-3=x\\
swap ~x~and~y\\
 \huge\underline{y=e^x-3}}
 \end{matrix}$

A sno-cone machine priced at $139 is on sale for 20% off. What is the price of the sno-cone machine after the discount? *

lawyer [7]

So percents are just written as 20% = 0.2 so keep that in mind

139 divided by 0.2 is 95 , which would be the price after the discount :)

hope this helps!
