The way you round is if it is below 5 you round down and if it is above 5 you round up so in the case of 750 it would go to 800 where if it was 749 it would go to 700
You would start at (0,36) and then move to (1, 24) , (2,12), (3,0) because he gives out 12 bags per hour
The vertex of f(x) = 3x^2 + 12x − 8 is (2,28) absolute minimum
<h3>How to determine the vertex?</h3>
The equation is given as:
f(x) = 3x^2 + 12x − 8
Differentiate the function
f'(x) = 6x + 12
Set to 0
6x + 12 = 0
Divide through by 6
x + 2 = 0
Solve for x
x = -2
Substitute x = -2 in f(x) = 3x^2 + 12x − 8
f(2) = 3 *2^2 + 12 *2 − 8
Evaluate
f(2) = 28
This means that the vertex is (2,28)
A quadratic function is represented as:
f(x) =ax^2 + bx + c
When a is positive, then the vertex of the function is an absolute minimum.
This means that f(x) = 3x^2 + 12x − 8 has an absolute minimum vertex because 3 is positive

The correct answer is C and D .
Answer:
analyzed & sketched
Step-by-step explanation:
We are given the function: y = In(x + 3)
So first we need to take the first derivative to find the interval of increase and decrease, then the second derivative to find the interval of concave up and concave down.
So it is always increasing function, and always concave down function.
Since it is a logarithmic function, x>3.
So, x = 3 is vertical asymptote.
I attached the sketch as a picture.
