Question

what is the domain of the function y equals 2 square root of

$y = 2 \sqrt{5 x - 5 }$

Answer 1

Answer:

Domain: x>=1

Step-by-step explanation:

what values of x make it work (square roots must be greater than or equal to zero)

sqrt (5x-5) >=0

square each side

5x-5 >=0

add 5 to each side

5x>=5

divide by 5 on each side

5x/5 >=5/5

x >=1
