Question

y= sqrt 3x

Domain
Range


y= sqrt (5x-3)

Domain
Range

Answer 1

do you know the domain of \[y=\sqrt{x}\]

Answer 2

basically, everything under the square root symbol has to be positive, so what does that mean for the domain?

Answer 3

lol, isn't it... \(y=\sqrt{3x}\)

Answer 4

y = sqrt 3x
D : 3x ≥ 0
x ≥ 0
R : y ≥ 0

y = sqrt (5x - 3)
D : 5x - 3 ≥ 0
x ≥ 3/5
R : y ≥ 0

lol ;p

Answer 5

it doesn't matter the sqrt(3) is a constant multiple
the function's domain depends on sqrt(x)

Answer 6

\[f(x)=\sqrt{3x}=\sqrt{3} \sqrt{x} \\ \text{ the domain depends on the } \sqrt{x} \text{ for this function }\]
