Question

find domain and range of f(x) = √4|| − 2 − 3​

Answer 1

Answer:

4x_5y

is the answer

hope this will help you

Answer 2

The domain would be all real numbers such that 4-3x

≥

0 Or such that 3x

≤

4, that is x

≤

4

3

. This is because the quantity under the radical sign cannot be any negative number.

For the range, solve the expression for x.

y-2=

√

4

−

3

x

Or,

4-3x=

(

y

−

2

)

2

, Or

y-2=

√

4

−

3

x

Since 4-3x has to be

≥

0

,

y

−

2

≥

0

Hence Range would be y ;

∈

R, y

≥
