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

CAN ANYONE HELP ANSWER THIS

Answer:

  58

Step-by-step explanation:

The marked points on the graph show that the number of hot cocoas sold decreases by 6 when the temperature goes up by 6 degrees. That is, the line has a slope of -1. The y-intercept is 100, so the equation of the line can be written as ...

  y = mx +b . . . . . line with slope m and y-intercept b

  y = -x +100

Then for x = 42, the expected value of y is ...

  y = -42 +100 = 58

Mei Mei can expect to sell 58 hot cocoas on a day when the high is 42°F.
