Determine the range and injective of the function.<br><br> j(x) = -x - 1

Nonamiya [84]

Answer and Step-by-step explanation:

Solution:

Range:

Let f(x) = -x-1

Here a=0 and b= -1, x=-b/a

Put the values, we get

X= - (-1)/0 = infinity

Hence the range of the function f(x) = (-∞, ∞)

Injective:

A function is said to be injective if f(x1) = f(x2), gives x1=x2

Let f(x1) = -x1-1

f(x2) = -x2-1

f(x1) = f(x2)
