please help me
y=(√(9−x^2 ))
Q find domain and range of given real function
i found the domain=[−3,3]
but for range i followed this way
y^2 =9−x^2
x^2 =9−y^2 ⇒x=(√(9−y^2 ))⇒y=[−3,3]
but the answer is [0,3]
after checking the graph y≥0. yes its true
we have to take positive root but how can i
write it
