Question

find the domain and range of f(x) = 1 / x-5 (can anyone help me, step by step )​

Answer 1

given

f(x) = 1 / x-5

solution

$= > f(x) = \frac{1}{x - 5}$

this domain

• (real number-5)

• {R-5}

• x≠5

when x value 5 to f(x) value indefine(∞)

=======================================

this range

• ( r-∞)

• =>f(x) =y ≠ ∞

=======================================

I hope it helps you
