What is the domain and range for the following function and its inverse f(x) = x^2 – 5

Step-by-step explanation:

hello :

the domain is : D = R = =]-∞;+∞[ ( all numbers reals)

let : f(x) = y

y = x² - 5

x² = y+5

x exist : y + 5 ≥ 0

y ≥ - 5

so : the inverse is  [-5;+∞[

r and t.

both are 64 degrees.
