Answer:
You have relative maximum at x=1.
Step-by-step explanation:
-Note that f' is continuous and smooth everywhere. f therefore exists everywhere on the domain provided in the graph.
f' is greater than 0 when the curve is above the x-axis.
f' greater than 0 means that f is increasing there.
f' is less than 0 when the curve is below the x-axis.
f' is less than 0 means that f is decreasing there.
Since we are looking for relative maximum(s), we are looking for when the graph of f switches from increasing to decreasing. That forms something that looks like this '∩' sort of.
This means we are looking for when f' switches from positive to negative. At that switch point is where we have the relative maximum occurring at.
Looking at the graph the switch points are at x=0, x=1, and x=2.
At x=0, we have f' is less than 0 before x=0 and that f' is greater than 0 after x=0. That means f is decreasing to increasing here. There would be a relative minimum at x=0.
At x=1, we have f' is greater than 0 before x=1 and that f' is less than 0 after x=1. That means f is increasing to decreasing here. There would be a relative maximum at x=1.
At x=2, we have f' is less than 0 before x=2 and that f' is greater than 0 after x=2. That means f is decreasing to increasing here. There would be a relative minimum at x=2.
Conclusion:
* Relative minimums at x=0 and x=2
* Relative maximums at x=1
Answer:
Maggie is incorrect.
Step-by-step explanation:
PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 <em>before</em> dividing.

Part A: First, list multiples for each number. The multiples of 5 are: 5, 10, 15, 20, 25 30, 35, 40, 45, 50, 55, 60, etc. The multiples of 12 are: 12, 24, 36,48, 60, etc. The least common multiple is the first common multiple between the two, in this case being 60. The LCM of 5 and 12 is 60.
Part B: SImilar to above, list all factors for each number. 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. 81: 1, 3, 9, 27, and 81. The greatest common factor is the highest common number, 9 in this case. The GCF of 72 and 81 is 9.
Part C: To rewrite, we need to take out the 9 by dividing. 72/9 is 8. 81/9 is 9. Therefore, we would get 9(8+9), to equal 153. Your answer here is 9( 8 + 9 ). Hope this helped!
Hello!
This is a question about multiplying to get a polynomial answer.
Here we can use two strategies, which will get you the same strategy.
One is using a Punnett Square, and the other would be FOILing.
I personally like Punnett Squares, but I will use FOILing for the sake of being online.
FOIL stands for First, Outside, Inside, Last, which describes how the terms should be multiplied.
Let's multiply the first terms.
(-d + e)(4e + d)
The outside terms.
(-d + e)(4e + d)
The inside terms.
(-d + e)(4e + d)
The last terms.
(-d + e)(4e + d)
Now you just add them together to find the polynomial.
There are three terms in the product, and the product is degree 2, since the highest degree of the equation (the highest power any term is raised to) is 2.
Hope this helps!
