Determine whether the ffunction X/(x^2-1) is odd even or neither
djyliett [7]

equation is:

f(x) = \frac{x}{ {x}^{2} - 1 }

so if its even f(-x) should be equal to f(x)

that means

f( - x) =   \frac{ - x}{  {( - x)}^{2}  - 1}  \\  \\ f( - x) =     - \frac{ x}{ {x}^{2}  - 1}

so f(x) is not equal to f(-x) so its not even

If its odd than f(-x) should be equal to -f(x)

- f(x) =  - ( \frac{ x}{ { x}^{2} - 1 } ) \\  - f(x) =    - \frac{ x}{ {x}^{2} - 1 }

so as we can see f(-x)= - f(x)

so the function is odd

Ans:function is odd and not even

Paraphin [41]

<u>Find fraction of snappers and catfish:</u>

1/3 + 2/9 = 3/9 + 2/9 = 5/9


<u>Find fraction of goldfish:</u>

1 - 5/9 = 4/9


4/9 = 40 goldfish

1/9 = 40 ÷ 4 = 10

Hello, can i please have help on this question thank you
cricket20 [7]

Answer:

Step-by-step explanation:

a) One can get maximum score when all the 20 questions answered are correct.

Maximum score = 20*3 = 60 points

b) Minimum score = 20 * (-2) = -40 points

c) Points for correctly answered questions = 10*3 = 30

Incorrectly answered questions = 14 - 10 = 4

Points for incorrectly answered questions = 4 * (-2) = -8

Total score = 30 + (-8) = 22

d) Points for correctly answered questions =5*3 =  15

Points for incorrectly answered questions = 13 * (-2) = -26

Total score = 15 + (-26) = -11

Quadratics formula 4x^2+3x-1=0
VARVARA [1.3K]

Answer: X = 1/4 or X = -1

Step-by-step explanation:

4x2+3x−1=0

(4x−1)(x+1)=0

4x−1=0 or x+1=0

4x=1 or x=-1

Now divide 4 from both sides

like this 4x/4=1/4

now cancel out two 4's so the answer will be x=1/4
