Answer:
Domain = all real numbers
Step-by-step explanation:
The domain of a function is the set of x-values for which the function is defined.
When we have a graphical representation of a function, we look if the function is continuous for all values of x or not. If it is, the domain is the set of all real numbers. If it is not, we look from what value till what value the function is defined for , x-values basically.
Looking at this function, we see that it stretches forever to the left and forever to the upward direction (also advancing right limitless as well).
We want the domain (x values), which concerns with LEFT and RIGHT. So, we can see that this function is continuous for all values of x (it goes on and on to right and left). So we can say the domain is the set of all real numbers.
Domain = all real numbers
The expression 12 - a represents the number of apples Sam gave away to his friends. Option D best describes this situation.
The expression 12 - a represents the number of apples Sam gave away to his friends.
Option D, 'Sam knows he had 12 apples to start. He does not know how many apples he gave away,' best describes this situation. In this case, Sam started with 12 apples but does not know the exact number he gave away.

Let
x--------> the number of weeks
y--------> the height of a pile of newspapers in inches
we know that
To find the height after weeks
Let
and substitute in the equation
therefore
the answer is
the height, in inches, of the pile after weeks is
graph of |x|=-5 is not possible.
We know that modulus makes everything inside it as positive.
To make the graph of equations with modulus functions, we need to make cases as to check the behavior of the modulus. In this:
CASE-1 :
when expression inside modulus is positive,i.e., x ≥ 0, ∴ |x| = x
Now, |x| = -5
x = -5 ; but we assumed x ≥ 0
So, this case is false.
CASE-2 :
when expression inside modulus is negative,i.e., x < 0, ∴ |x| = -x
Now, |x| = -5
-x = -5
x = 5 ; but we assumed x < 0
So, this case is also false.
In these two cases all the real possible values of x is covered.
Therefore no real value of x satisfies the equation. So, this is false and no graph for it is possible.
