and gives a unique corresponding output.
There is a special notation, called "function notation," that is used to represent this situation:
if the function name is f , and the input name is x ,
Step-by-step explanation:
Answer:
(-∞,0)∪(0,∞)
Step-by-step explanation:
The domain of a function is wherever the y values exist. The only time the y values dont exist in this function is when the denominator is zero. So the denominator does not exist at x=0, because that is when 4x = 0.

x < 22.5; Samuel has less than 22.5 minutes to finish the race in the estimated time.
<h3>What amount of time Samuel left for the race?</h3>
The given inequality is-

From here, we define the variable x.
x = Number of the minutes left for the race
From here we can find the value of x
We have then:


Hence, Samuel has less than 22.5 minutes to finish the race in the estimated time.

Answer:
the slope is 3/5
Step-by-step explanation:
We can find the slope from two points using the formula
m = (y2-y1)/(x2-x1)
= (4-1)/(12-7)
= 3/5
