Question
The area A enclosed by a square, in square inches, is a function of the length of one of its sides x, when measured in inches. This relation is expressed by the formula A(x) = x^2 for x > 0.Find the domain of the function A(x): The area A enclosed by a square, in square inches, is a function of the length of one of its sides x, when measured in inches. This relation is expressed by the formula A(x) = x^2 for x > 0.
Find the domain of the function A(x):
Find the domain of the function A(x):
Explanation / Answer
A(x) = x^2
x>0 then x^2 >0
so domain of area A(x) is (0,infinity)
domain (0,infinity)
