Find the domain and range of the following functions f(x) = 1 x 2 Solution For any values values of x, the function will give defined values It will never become undefined So, domain is all real values that is R The range of x 2 lies between 0 to ∞ But we need find the range of 1 x 2 0 ≤ x 2 ≤ ∞ Multiplying by negative through out the inequality, we get ∞ ≤ x 2 ≤ 0 Add 1The domain and range of the function f= ((1/1x2)) x ∈ R, x ≠ ± 1 are respectively Q The domain and range of the function $f=\left\{\left(\frac{1}{1x^{2}}\right) x \in R, x \ne \pm 1There are no restrictions on domain The domain is (,) Since the value of x is squared, f(x) will always be equal or greater than 0
Example 1 Find the domain and range of the following functions f(x) = 1/(2 sin 3x) Solution In order to find the domain, let us equate the denominator to 0 2 sin 3x = 0 sin 3x = 2 This is impossible, because the minimum value of sin is 1 and maximum value is 1–1 x 2 4 y 021 Mathematics Learning Centre, University of Sydney 5 State its domain and range Solution The function is defined for all real xThe vertex of the function is at (1,1) and therfore the range of the function is all real y ≥ 1 12 Specifying or restricting the domain of a functionY = f (x) = (1 − x 2) 1 For range, y = (1 − x 2) 1 ⇒ y − y x 2 = 1 ⇒ y x 2 = y − 1 ⇒ x 2 = y y − 1 ⇒ x = ± y y − 1 ∴ y = 0 The term under the root has to be positive casei caseii
