Maths-Domain and Range-Understanding Simple and Easy (O-Level) 

Basically you dont pay attention or its your exam tomorrow so your studying hard

​@@wasa69right

same lol

@@wasa69no need to shame anybody you nerd😂😂😂

​@@wasa69But it is hard to pay attention without understanding.

Giga nigga

Isi lia domain greater and equal to 2 i h k x ki values 2 ya to s greater honi chaea...

Domain - domain is all the possible x values that can be inputted a rule So if there was a sqrt above the varible like f(x) = sqrt(x) it cant be negative because you cant find the sqrt of a negative number, so negative numbers are not included in the range. So it would be x >0/ = 0. Range is the same but instead of it being all the possible x values, its all the possible ys. This relies on the domain as the y /dependent variable typically does Using the last example but adding an + 5 to the expression y would be =5 or >5.

@@Yeahitisminewha? I’m not a kid and I didn’t understand it either, his explanation was amazing

No , -ve numbers,0,1 can't be used in this function.

all postive real numbers starting from 2

Range [1,♾️)

But the square root is only on x-2, that's why!

what if x is equal to 2, that would be 0 + 1 which will give 1. So the range is correct, y has to be greater than or equal to 1.

@@sad1m.yes because if we add 2 to x then the answer is going to be 0 , so 0 + 1 = 1 then the range should be greater than or equal to 1

Pls provide the method you used .. cuz his answer is correct and if you put x=3 f(3)= root 1 +1 = 2 He is correct

you can put x = 2 or greater than 2

Root is a positive function, so it can't give negative outputs. Hence the underoot of 3 will be +1.732 and not -1.732
