Answer:
The vertical line test is a way for you to see if a graph represents a function. It allows you to identify if any x values have more than one y value.
A graph would be a function if every input (x) has exactly one output (y). A graph would not be a function if an input (x) has more than one output (y).
Step-by-step explanation:
In a function, every input within the domain of the function must have exactly one output. If the graph has an input that has more than one output, then it is not a function. The vertical line test is what allows you to see if a graph is a function or not.
Answer:
Yes, in places like the US, UK and other bigger areas
No, in like Africa and poorer areas
Answer:
Option A is correct, i.e. 12.
Step-by-step explanation:
Given is the table of x&y relationship which represents an exponential function.
The average rate of change for a function can be found using the following formula:-
F_average = { f(b) - f(a) } / (b-a)
Given a = 3 and b = 5.
From the table, f(3) = 8 and f(5) = 32.
So, F_average = (32-8)/(5-3)
F_average = 24/2 = 12.
Hence, option A is correct, i.e. 12.
Answer:
To calculate the mean we need x and f both
Answer
Step-by-step explanation:
If you deposit money, your bank account shows it as +3
3 degrees below zero = - 3 o F which is darn cold.
3 floors below ground level = - 3 floors below ground level
3 feet above sea level = +3 feet
3 degrees about 0 = + 3
3 dollars lost = -3 dollars.
