What’s the non-permissible value for x^2-x-2

x = -1 and x = 2 are non-permissible

Step-by-step explanation:

for rational equations, the denominator can't equal zero, so find the zeroes of the equation, those will be the non-permissible numbers...

take the denominator and set it equal to zero, then solve...

x² - x - 2 = 0

(x - 2)(x + 1) = 0

so

x - 2 = 0

    x = 2

and

x + 1 = 0

   x = -1

Either of these values make the denominator equal zero, so they are not part of the domain of the function (non-permissible numbers)

step-by-step explanation:

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
