Question

the domain of f(x)=√x+ 2​

Answer 1

Answer:

[-~,-2) union [0,~)

Step-by-step explanation:

f(x)=√(x+2)

for f(x) To be defined the term under the square root should be greater than or equal to zero...

x+2 greater than equal to (>-) 0

x<- (-2)

so the domain is [-~,-2)

for x+2>-0

√(x+2)>-0

y>-0

range is [0,~)

this is your answer

hope it helps you
