Question

What are the domain and range of the function f(x)=logx-5?

Answer 1

Answer

Domain is (5, ∞), {x| x is greater than 5} for all integer n

Range is (-∞, ∞), {y| y belongs to Reals numbers}

Explanation

$F(x) = log (x - 5)$

Set up the equation for x

$x - 5 > 0$

or,

x > 5

So the domain is all values of x greater than 5 to infinity.

Range is set of all correct or valid values of y.

Range = (-∞, ∞), {y| y belongs to Reals numbers}
