Answer 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 answerRange set includes those values of f (x) (called functional values) for which x is in the domain That is all the numbers that can be generated from this function f (x)= (x3)/ (2x1) for each x in the domain Example , put x=1 then f (1)= (2/3) So (2/3) is a member of the range setWhat is the domain and range of the real function f(x)=1/(1x^2)?

Find The Domain And Range Of The Real Function Defined By F
Rational functions f(x) = 1/x have a domain of x ≠ 0 and a range of x ≠ 0 If you have a more complicated form, like f(x) = 1 / (x – 5), you can find the domain and range with the inverse function or a graph See Rational functions Sine functions and cosine functions have a domain of all real numbers and a range of 1 ≤ y ≤ 1All real y ≥ 0 Example a State the domain and range of y = √ x4 b SketchWhen the given function is of the form f(x) = 2x 5 of f(x) = x 2 – 2, the domain will be "the set of all real numbers When the given function is of the form f(x) = 1/(x – 1), the domain will be the set of all real numbers except 1 In some cases, the interval be specified along with the function such as f(x) = 3x 4, 2 < x < 12
From the graph, we can observe that the domain and the range of the function are all real numbers except 0 So, the domain and the range of f (x) = 1 x f ( x) = 1 x is R/{0} R / { 0 } Example 3 Ms Amy asked her students to find the range and domain of the function given on the boardThe "" means "such that," the symbol ∈ means "element of," and "ℝ" means "all real numbers" Putting it all together, this statement can be read as "the domain is the set of all x such that x is an element of all real numbers" The range of f (x) = x2 in set notation is R {y y ≥ 0} R indicates rangeArithmetic Mean Geometric Mean Quadratic Mean Median Mode Order Minimum Maximum Probability MidRange Range Standard Deviation Variance Lower Quartile Upper Quartile Interquartile Range Midhinge Standard Normal Distribution f(x)=\frac{1}{x^2} domain\y=\frac{x}{x^26x8} domain\f(x)=\sqrt{x3} domain\f(x)=\cos(2x5) domain\f(x
