A function may be thought of as a rule which takes each member x of a set and assigns, or maps it to the same value y known at its image x → Function → y A letter such as f, g or h is often used to stand for a functionThe Function which squares a number and adds on a 3, can be written as f(x) = x 2 5The same notion may also be used to show how a function affects particular valuesA math reflection flips a graph over the yaxis, and is of the form y = f (x) Other important transformations include vertical shifts, horizontal shifts and horizontal compression Let's talk about reflections Now recall how to reflect the graph y=f of x across the x axisGraph and Formula of f(x) g(x) Discover Resources Algebra Assignment 408;

How to get f'(x)
How to get f'(x)-That is, the rule for this transformation is –f (x) To see how this works, take a look at the graph of h(x) = x 2 2x – 3F (x) is the graph we are given To go from f (x) to f (x), change the sign of each xvalue in the f (x) function Going from f (x) to f (x) would give us a reflection over the xaxis Going from f (x) to f (x) is what we need to do, and this will be a reflection over the yaxis Figure out how far each point in f (x) is from the yaxis

Since the input \(x\) can be any real number the range of \(f\) is all the integers, \(\mathbb{Z}\) The function \(g(x)=xx\) which means it subtracts the whole number part, leaving only the fractional part of the input value \(x\) For integer values of \(x\), \(x=x\) which means that \(g(x)=0\) So the graph of the function looks like thisIf range = f (x)a < f (x) < b, then the new range is g(x)b < g(x) < a Graphs of f (x) and f (x) Making the input negative reflects the graph over the yaxis, or the line x = 0 Here are the graphs of y = f (x) and y = f ( x)Purplemath The last two easy transformations involve flipping functions upside down (flipping them around the xaxis), and mirroring them in the yaxis The first, flipping upside down, is found by taking the negative of the original function;
So let's start with the function f of x =4x I'm going to graph that function and then I want to graph f of 4x So let's make this our parent function it's actually pretty easy to come up with values for it and you know what the shape is going to be, it's a radical function So I'll make this u and root 4u, let's pick values to plug in that'll• The graph of f(x)=x2 is a graph that we know how to draw It's drawn on page 59 We can use this graph that we know and the chart above to draw f(x)2, f(x) 2, 2f(x), 1 2f(x), and f(x) Or to write the previous five functions without the name of the function f,Graph f (x) = square root of x f (x) = √x f ( x) = x Find the domain for y = √x y = x so that a list of x x values can be picked to find a list of points, which will help graphing the radical Tap for more steps Set the radicand in √ x x greater than or equal to 0 0 to find where the expression is defined x ≥ 0 x ≥ 0

The derivative of a function y = f(x) of a variable x is a measure of the rate at which the value y of the function changes with respect to the change of the variable x It is called the derivative of f with respect to x If x and y are real numbers, and if the graph of f is plotted against x, derivative is the slope of this graph at each point¡12, so we know that the graph of f(x) is concave down at x = 0 Likewise, at x = 1, the second derivative of f(x) is f00(1) = 18 ¢1¡12 = 18¡12 = 6;Intuitively, a function is a process that associates each element of a set X, to a single element of a set Y Formally, a function f from a set X to a set Y is defined by a set G of ordered pairs (x, y) with x ∈ X, y ∈ Y, such that every element of X is the first component of exactly one ordered pair in G In other words, for every x in X, there is exactly one element y such that the
