Find an answer to your question "What are the domain and range of the function f (x) = 3X 5?O domain (00,00);Find the Domain and Range f (x)=5 f (x) = −5 f ( x) = 5 The domain of the expression is all real numbers except where the expression is undefined In this case, there is no real number that makes the expression undefined Interval Notation (−∞,∞) ( ∞, ∞) Set Builder Notation {xx ∈ R} { x x Explanation The denominator of f (x) cannot be zero as this would make f (x) undefined Equating the denominator to zero and solving gives the value that x cannot be solve x = 9 = 0 ⇒ x = 9 ← excluded value ⇒ domain is x ∈ R,x ≠ 9 for the range rearrange making x the subject y = 5 x −9

F(x)=2x+5 domain and range
F(x)=2x+5 domain and range-In f(x) = 5(x3)²= x²6x4 , x has no impediment in the Real scale so the domain must be all Real x In the range we see that for f(x)=0 there are the real roots x=(6±√)/2 and just as with the domain no reason to except any Real numbers in the range either, now we check for maxima and/or minnima f'(x)=2x6 and when x=3 and f(x)=5 there's a maximum so the domain in the positive Identify the vertex, axis of symmetry, minimum or maximum, domain, and range of the function f(x) = (x 4)2 – 5 Categories Uncategorized Leave a Reply Cancel reply Your email address will not be published Required fields are marked * Comment Name * Email *

For this function any whole number is okay,then use PEMDAS to compute the range Good rule of thumbs on domain and range constants have any number as the domain f(X)= 7, then (1,7),(2,7),(3,7) Linear functions in the slope intercept method neGiven f(x) = x 5 ∀ x є R To Find Domain and Range of f(x) The domain of the given function is all real numbers expect where the expression is undefined In this case, there is no real number which makes the expression undefined As f(x) is a polynomial function, we can have any value of x Therefore, Domain(f) = (∞, ∞) {x x є RTo ask Unlimited Maths doubts download Doubtnut from https//googl/9WZjCW Find domain and range of `f(x)=x/(1x^2)`
To find the range we have to study the behavior for x → ± ∞ lim x→−∞ f (x) = lim x→ −∞ 5 x − 9 = 5 −∞ = 0− lim x→∞ f (x) = lim x→ ∞ 5 x − 9 = 5 ∞ = 0 Then y = 0 is a horizontal asymptote Indeed, f (x) ≠ 0∀x ∈ FE x → 9±One way to include negatives is to reflect it across the x axis by adding a negative y = x^2 With this y cannot be positive and the range is y≤0 The other way to include negatives is to shift the function down So y = x^2 2 shifts the whole function down 2 units, and y ≥ 2 Transcript Example 21 Find the domain of the function "f" (x) = (" " 2 3 5)/( 2 5 4) "f" (x) = (" " x2 3x 5)/(x2 5x 4) = (x2 3x 5)/(x2 4x 4) = (x2 3x 5)/( (x 4) 1( 4)) = (x2 3x 5)/(( 4)(x 1) ) In real numbers , the denominator cannot be zero Hence (x 4) (x 1) 0 x 4 and x 1 Hence the domain of the function will be all real numbers except 1 and 4 Hence, the domain
Domain and range The domain and range of a function is all the possible values of the independent variable, x, for which y is defined The range of a function is all the possible values of the dependent variable y The example below shows two different ways that a function can be represented as a function table, and as a set of coordinatesArrow_forward Question View transcribed image text fullscreen Expand check_circle Expert Answer Want to see the stepbystep answer?Answer to Find the maximal domain and range of the function f, given by f(x) = \sqrt{5 4x x^2}, and sketch its graph By signing up, you'll get

For the square root function latexf\left(x\right)=\sqrt{x}/latex, we cannot take the square root of a negative real number, so the domain must be 0 or greater The range also excludes negative numbers because the square root of a positive number latexx/latex is defined to be positive, even though the square of the negative number latex\sqrt{x}/latex also gives us latexx/latexIf f(x) = 3x 4, find f(5) and f(x 1) f(5) = 3(5) 4 = 19 f(x 1) = 3(x 1) 4 = 3x 7 Domain and Range The domain of a function is the set of values which you are allowed to put into the function (so all of the values that x can take) The range of theWhat is domain and range?
