How do you solve 27?
dedylja [7]

We have

\left(\dfrac{2}{3}\right)^x=\dfrac{2^x}{3^x}

And we want

\dfrac{2^x}{3^x}=\dfrac{16}{81}=\dfrac{2^4}{3^4}

Another way to read it is

\dfrac{16}{81}=\left(\dfrac{2}{3}\right)^4=\left(\dfrac{2}{3}\right)^x

It should be clear that the solution is x=4

What is the domain of the function represented by the graph?
Natalija [7]

The domain of given function is: -3≤x≤3

Step-by-step explanation:

The domain is the set of all possible inputs of the graph. In a graph, the input values are plotted on x-axis and the output or range is plotted on y-axis.

In the given figure we can see that the x-values that are involved in the graph of function are between -3 and 3. So the domain of the function will be:

-3≤x≤3

Hence,

The domain of given function is: -3≤x≤3

Keywords: Domain, Range
