Answer:
Step-by-step explanation:
Given
--- volume
Required
The surface area as a function of base length
The volume (V) is calculated as:
Make y the subject
Substitute 3 for V
The surface area of the open box is:
Substitute:
Hence, the function is:
Answer:
You are correct.
Step-by-step explanation:
What you do is you add them together which is 2x and it stays in the square root. You are correct.
The domain of a function is the set of input or argument values for which the function is real and defined.
So, for the given function to be defined, we need to find the possible values for which the values of x makes the square root to be positive.
That is;
-9 -5x ≥ 0
Now, let's solve for x
Add 9 to both-side of the equation
-5x ≥ 9
Divide both-side by -5
x ≤ -9/5
Therefore, the domain of the function can be represented in interval notation as: ( - ∞ , -9/5]
