What is the domain of the function f(x)= √x+6-7

x≥1

Step-by-step explanation:

f(x) = √x+6-7

f(x) = √x-1

The value under a square root must be non-negative; therefore make the inequality x-1 ≥ 0 and solve it.

x ≥ 1

There's your domain! Hope this helps! :D

Step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
