√画像をダウンロード f(x)=(x-1)(x-2)(x-3) is one one or onto 575994

We note that there are point, x1 and x2 with x1 ≠ x2 and f (x1) = f (x2), for instance, if we take x1 = 2 and x2 = 1/2, then we have f (x1) =2/5 and f (x2) =2/5 but 2 ≠ 1/2 Hence f is not oneone Also, f is not onto for if so then for 1∈R ∃ x ∈ R such that f (x) = 1 which gives x/ (x21) =1The function f R → R defined by f(x) = 2x 1 is surjective (and even bijective), because for every real number y, we have an x such that f(x) = y such an appropriate x is (y − 1)/2 The function f R → R defined by f(x) = x 3 − 3x is surjective, because the preimage of any real number y is the solution set of the cubic polynomialIs x^3 x onetoone and onto?

[新しいコレクション] f(x)=5^x domain and range 280874-F(x)=6/x-5 find the domain and range

Jun 25,  · Answer Stepbystep explanation Hi, the function is defined for all reals so the domain is for x real x >= 0 so f(x) >= 4 so the range isFind the Domain and Range 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 SetBuilder NotationSep 23, 16 · We have, f x = x 5 x 5 Clearly f x is defined for all x ∈ R except at x = 5 So, domain of f = R5 Now, f x = x 5 x 5 ⇒ f x = x 5 x 5 = 1, when x > 5 and f x = x 5 x 5 = 1, when x < 5 So, range of f = 1, 1
