its a parabola , ( you can tell because one fo the variables is squared, a parabola will have either a minimum or maximum value

range of parabola is the range of valid y values!!

put x=2 in the given equation you will be left with only y=2 means regardless values of x it will be y=2 now since it is Parabola which opens upward . so can you tell me what will be the range ?

Did you find any value of x for which f(x) is undefined?

no its not right huh? @sami21 said yes

yep!! none of the real value of x make f(x) undefined!! So all real values of x make f(x) valid!! Therefore, what do you say about the range of y?

all real numbers

helpingtutors Group TitleBest ResponseYou've already chosen the best response.0
Yes.. so, since the term containing x is squared. f(x) retains a minimum of 2

hence, y has a restriction on real numbers as well!!

so what is that you say now on range of y??
 one year ago

sara1234 Group TitleBest ResponseYou've already chosen the best response.0
so the answer is all real numbers?

when you put x=2 you are left with y=2 this means whatever the value of x vale of y (range) will never be less than 2 .
