F(x) = x/1+x2
F(x) = x/1+x2-The maximum occurs where the denominator x^2 2 is at a mininum Clearly, x^2 2 must have a minimum of 2, because x^2 is either 0 or positive So the maximum value of f(x) is 1/2, and occurs at x = 0 On the other hand, there is no minimum, becThe known derivatives of the elementary functions x 2, x 4, sin(x), ln(x) and exp(x) = e x, as well as the constant 7, were also used Definition with hyperreals Relative to a hyperreal extension R ⊂ ⁎ R of the real numbers, the derivative of a real function y = f ( x ) at a real point x can be defined as the shadow of the quotient ∆ y / ∆ x for infinitesimal ∆ x , where ∆ y = f

Putting f(x1) = f(x2) we have to prove x1 = x2 1/x1 = 1/x2 x2 = x1 x1 = x2 Hence, if f(x1) = f(x2) , x1 = x2 ∴ f is oneone Check onto f N → R* f(x) = 1/x Let y = f(x) , , such that y ∈ R* y = 1/𝑥 x = 1/𝑦 Since y is real number except 0, x cannot always be a natural number Example Let y = 2 x = 1/2 So, x is not a natural number Hence, f is not ontoAlgebra 1 How to find f(x) Study concepts, example questions & explanations for Algebra 1 CREATE AN ACCOUNT Create Tests & Flashcards Home Embed All Algebra 1 Resources 10 Diagnostic Tests 557 Practice Tests Question of the Day Flashcards Learn byNotice that the main points on this graph are \(x = 2,\,1,\,4\) Graph of y = f(x) k Adding or subtracting a constant \(k\) to a function has the effect of shifting the graph up or down
