F(x) = x – 2 Consider c > 1 and f(c) = c – 2 \(\lim_{x \rightarrow c}f(x) = \lim_{x \rightarrow c}x2 = c2\) Thus, the function f(x) is continuous at all real numbers greater than 1 Case 3 When x = 1, f(x) = x 2 Consider c = 1, now we have to find the lefthand and righthand limits LHL \(\lim_{x \rightarrow 1^}f(x) = \lim_{x \rightarrow 1^}x2 = 12=3\) RHLFunctions are given letter names The names are of the form f(x) which is read "f of x" The letter inside the parentheses, usually x, stands for the domain set The entire symbol, usually f(x), stands for the range set The orderedpair numbers become (x, f(x))So we can see that when x is equal to zero, f of x is equal to one, so g of x should be equal to two because it's two times f of x So g of x is going to be equal to Or g of zero, I should say, is going to be equal to two What about when at x equals, we'll say when x equals three When x equals three, f of x is negative two

F (x)= WolframAlphaExample 1 f(x) = x We'll find the derivative of the function f(x) = x1 To do this we will use the formula f (x) = lim f(x 0 0) Δx→0 Δx Graphically, we will be finding the slope of the tangent line at at an arbitrary point (x 0, 1 x 1 0) on the graph of y = x (The graph of y = x 1 is a hyperbola in the same way that the graph of yA function like f ( x, y) = x y is a function of two variables It takes an element of R 2, like ( 2, 1), and gives a value that is a real number (ie, an element of R ), like f ( 2, 1) = 3 Since f maps R 2 to R, we write f R 2 → R We can also use this "mapping" notation to define the actual function We could define the above f ( x
In the given example, we derive the derivatives of the basic elementary functions using the formal definition of a derivative Let us assume that y = f (x) is a differentiable function at the point x_0 Then the derivative of the function is = f' (x_0) = Here "the derivative of the function at " Examples of mathematical functions include y = x 2, f(x) = 2x, and y = 3x 5 Any mathematical statement that relates an input to one output is a mathematical function Let's clarify more about this by using an example Take a look at the relation between the radius (r) of a circle and its area, A=πr2 Let's say I'm interested in finding A given an r For instance, if I was given an r of 1 (input) into πr 2 (function), it will give me π square units (output)

It is a different way of writing "y" in equations, but it's much more useful!The borderline situation f0(x) = 1 needs to be looked at on a casebycase basis (may be attracting, repelling, or show mixed behaviour) Now we can review our previous examples in this light Examples f(x) = x 2 1 x has a xed point at x = p 2, and f0(p 2) = 0 So this is very very attracting f(x) = 5 2 x 3 2 xExplanation \displaystyle f (x) = 3 \sqrt {x1} \displaystyle f (13) = 3 \sqrt {131} = 3 \sqrt {12} \displaystyle g (x) = 3 \sqrt {x1} \displaystyle g (13) = 3 \sqrt {131} = 3 \sqrt {12} The easiest way to find \displaystyle \left (fg \right ) (13)
