f(x) = 1/√(x+2)
|dw:1381879217098:dw|
What do want to do with the function? Find what x is or something?
it says Based on the definition of the function f above for which of the following value of x is f NOT defined ?
it's multiple choice a) -2 b) -1 c)0 d)1 e)2
Ok so a time when a function is undefined is when you have a number divide by zero like\[\frac{ 1 }{ 0 }\] So when does x in the denominator = to 0?
the "domain" for the function, that is, values "x" can safely take, are, in cases of radicals, the values that WILL NOT MAKE THE RADICAL negative in case of rationals, are the ones that WILL NOT MAKE THE FRACTION UNDEFINED
so which one is a answer a) -2 b) -1 c)0 d)1 e)2
x+2=0 what is x? and that is your answer
so it's gonna be -2 (right? )
Yep
thanks alot for helping me
No problem hope it helps and good luck :)
