Answer:
(9/5, 8/5)
Step-by-step explanation:
First you want to find the equations of the lines. One line is y = 2x - 2 and the other line is y = 1/3x + 1. Then you want to find the x and y that both work in the two equations.
y = 2x - 2
y = 1/3x + 1
Then you do 2x - 2 = 1/3x + 1
Then you do some maths and you get 9/5, and 8/5
Answer:
C7,3=7!( 3!)( 7−3)!= 7! I think tell me if I'm wrong?
For this case we have the following definitions:
A function is even if, for each x in the domain of f, f (- x) = f (x). The even functions have reflective symmetry through the y-axis.
A function is odd if, for each x in the domain of f, f (- x) = - f (x). The odd functions have rotational symmetry of 180º with respect to the origin.
We then have the following function:
![f (x) = 9 - 4x ^ 2](https://tex.z-dn.net/?f=%20f%20%28x%29%20%3D%209%20-%204x%20%5E%202%20%20)
Applying the definitions we have:
![f (-x) = 9 - 4 (-x) ^ 2\\f (-x) = 9 - 4 (x) ^ 2\\f (-x) = f (x)](https://tex.z-dn.net/?f=%20f%20%28-x%29%20%3D%209%20-%204%20%28-x%29%20%5E%202%5C%5Cf%20%28-x%29%20%3D%209%20-%204%20%28x%29%20%5E%202%5C%5Cf%20%28-x%29%20%3D%20f%20%28x%29%20%20)
Answer:
The function is not odd because it is fulfilled:
![f (-x) = f (x)](https://tex.z-dn.net/?f=%20f%20%28-x%29%20%3D%20f%20%28x%29%20%20)
Therefore, the function is even.
