For just n I’m pretty sure it’s 4n
I am using the Descartes Rule of Signs.
f(x) = 3x^4 - 5x³ - x² - 8x + 4
positive zero: 2 or 0.
x = + - - +
There are 2 sign changes : + to - ; - to +.
negative zero: 1.
f(-x) = 3(-x^4) - 5(-x³) - (-x²) - 8(-x) + 4
f(-x) = 3x^4 + 5x³ - x² + 8x + 4
-x = + + - + +
there is only 1 change of sign. - to +.
There are 2 or 0 positive solutions and 1 negative solution.
Answer:
5 containers
Step-by-step explanation:
Alica has 20 cups of soup. She wants to put the soup into 1 quart containers. How many containers does she need?
It is important to note that:
4 cups = 1 quart
Hence, the number of containers she needs is calculated as:
4 cups = 1 quart
20 cups = x
Cross Multiply
4x = 20
x = 20/4
x = 5 quarts containers
Therefore, she needs 5 containers
I'm not sure what you want.
