√ f(x)=√9-x^2 find domain and range 169298-If f(x)=(x^(2)-9)/(x-3) find its domain and range

Say, f (x)= √ (x²9) Clearly, for any real value of x, x² >0 and thus x²9>0,ie, f (x)>0, which implies √ (x²9) is defined for every real value of x So, the domain of the function f (x) is (∞,∞)To ask Unlimited Maths doubts download Doubtnut from https//googl/9WZjCW Find the domain and range of, `f(x) = 2x33` Find the domain and range of f(x)=x/x^29 1 See answer Torpekai is waiting for your help Add your answer and earn points

Let y = f(x) be a function Range is all real values of y for the given domain (real values of x) Let us look at some practice questions to understand how to find domain and range of a function Practice Questions Question 1 Find the domain of 1 / (1 − 2sinx) Solution 1 − 2sin x = 0 2sin x = 1 sin x = 1/2 sin x = sin π/6Correct Answer Option (b) Here we get that, no two elements of the domain has the same image and no element of codomain is the image of more than one element in the domain ∴ f is oneone Let's prove that f (x) = x2 is not onto Hence, for y = 3 ∈ N there does not exist any x ∈ N such that f (x) = y ∴ f is not onto Find the domain of the function \(f(x)=x^2−1\) Solution The input value, shown by the variable x in the equation, is squared and then the result is lowered by one Any real number may be squared and then be lowered by one, so there are no restrictions on the domain of this function The domain is the set of real numbers In interval form, the domain of f is
