Which of the following graphs could be the graph of the function f(x) = x4 + x3 – x2 – x?
Sav [38]
For this case we have the following function:
 x ^ 4 + x ^ 3 - x ^ 2 - x

 We can rewrite the function to identify the zeros of it.
 When rewriting the function factoring we have: x (x-1) (x + 1) ^ 2

 Therefore, the zeros of the function are:
 x = 0

x = 1

x = -1
 Thus, the graph that contains intersections on the x axis in the points mentioned, will be the graph of the function.

Louis started a table showing a multiplication patterns complete the table describe a pattern you see in the products
kvasek [131]
One pattern that you can see in a multiplication table is the perfect square numbers. It runs from the top left hand corner directly through the middle to the bottom right hand corner. A perfect square is a number that is multiplied by itself. The perfect square numbers are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144. They keep going forever on but those are the main ones from 1x1 to 12x12.

ANEK [815]
Y = 0.213x – 352.0 <span> represents this linear model shown in the data table.
Plug in the values of x into the equation for a double check.
Let's try 1980.

</span><span>y = 0.213(1980) – 352.0
</span>y = 69.74
which is closest to the 70.1 whereas other options do not satisfy the condition.

An acute triangle has two sides measuring 8 cm and 10 cm . What is the best representation of the possible range of values for t
Mekhanik [1.2K]

Answer:

the right answer is 2 < s< 18

Step-by-step explanation:

The Third side of the triangle must be greater than the difference of the other two sides which is 10 -8= 2 and smaller than the sum of the other two sides of the triangle which is 10+8= 18.

so third side should be greater than 2 and less than 18.

So right answer is 2 < s< 18
