This is a little something you have to memorize, but you could derive it from the equation pb = 2π. In the parent function, the b value is 1, so the period, p, is equal to 2π/1 or just 2π.

What is the domain and range for the following function and its inverse? f(x) = -x + 5

iren2701 [21]

Answer:

Domain: $\mathbb{R}$

Inverse: $f^{-1}(x) = -x + 5$

Step-by-step explanation:

Since this is a linear function, the domain and range is simply the set of real numbers.

The inverse is obtain by switching the places of x and y, then solving for y.

Here,

y = -x + 5

So switching x and y,

x = -y + 5

Solving for y again,

y = -x + 5

Thus,

$f^{-1}(x) = -x + 5$
