Answer with Step-by-step explanation:
We are given that a function

Assign each whole number to its largest place value digit.



We have to find the value of x that makes the equation 7 a true statement.
When f(x)=7
Then, the possible values of x are 7,127,27,257,... .
Because f(7)=7
f(127)=7
f(27)=7
f(257)=7
Therefore, the value of x =7,127,257,27,..
According to the given graph, we can note the following:
The domain would be all the real numbers that
