Jul 12, 18 · For the given function f (x) = 10x LH L = RH L = f (x) ie f (x) = 10x is continuous everywhere hence its domain the set of real numbers ie x ∈ R or x ∈ ( −∞,∞) Now, range of function is determined as lim x→−∞ f (x) = lim x→ −∞ 10x = 0 lim x→∞ f (x) = lim x→ ∞ 10x = ∞ hence the range of function f (xAnswer Under square root the polynomial must be positive The domain is obtained by solving You can obtain the zeroes of the polynomial So the polynomial is solved in the external intervals Since the function f (x) is positive, due to result of square root, The range includes all positive real numbers x≥ 0 Hence, this is the answerFeb 15,  · Hello sir, Please explain this sum, Find the domain of the functions i) f(x) = 1/√(x^2 5x 6) ii) f(x) = x^22x1/x^28x12 4x1 then x = mod(2xx)=4 where represent greatest integer function find domain of √x^25x6 Find range
