Answer:
t=2.25
Step-by-step explanation:
You want to find out what t is.
If 4t = 9, the how much is t?
First step is to divide 9 by 4.
When you divide 9 by 4, you find out how much t is.
When you divide 9 by 4, you get 2.25, or 2 1/4
Domain: The set of all real numbers
We can plug in any x value we want and there aren't any restrictions. There aren't any holes, jumps, gaps, or asymptotes
-------------------------------------------------
Range: Only one value is in the range and it is the value 2. We can write this as {2}. The curly brackets indicate "set". It is possible to have a set of only 1 item inside.
The range is the set of y value outputs. In this case, the output is 2 because we have a horizontal line. No matter what the x input is, the output is always 2. This is known as a constant function. The output is constantly the same.
