Answer:
See Graph Below
Domain: All Real Numbers
Range: All Real Numbers
Step-by-step explanation:
For the graph, simply make your first point at 7 (the y-intercept) and then move 4 y's up for every x.
For the Domain: The answer would be all real numbers because you can plug any real number into x and the equation would be solvable.
For the Range: The answer would be all real numbers because there is no y that is impossible to reach via x.

Explanation:
Plug in the lower bound of the domain, which is x = -3
f(x) = 3x+2
f(-3) = 3(-3)+2
f(-3) = -9+2
f(-3) = -7
If x = -3, then the output is y = -7. Since f(x) is an increasing function (due to the positive slope), we know that y = -7 is the lower bound of the range.
If you plugged in x = 5, you should find that f(5) = 17 making this the upper bound of the range.
The range of f(x) is -7 < y < 17
Recall that the domain and range swap places when going from the original function f(x) to the inverse
This swap happens because how x and y change places when determining the inverse itself. In other words, you go from y = 3x+2 to x = 3y+2. Solving for y gets us y = (x-2)/3 which is the inverse.
-----------------------
In short, we found the range of f(x) is -7 < y < 17.
That means the domain of the inverse is -7 < x < 17 since the domain and range swap roles when going from original to inverse.
Step-by-step explanation:
Let us assume that the amount deposited = P
The rate of interest = 1.4%
The Simple Interest earned = $24.50
Time = T = 5 years
Now, as we know:
SIMPLE INTEREST =
Hence, the deposited sum of money by Edwin is $350.
