The will worksheet will discuss the concept of relations and functions. Determine the domain and range and state whether the relation is a function or not. Chapter 3: Introduction to Functions and Relations. Math is often viewed as a difficult and boring subject, however, with a little effort it can be easy and interesting. As every value of x has a different value of y; it is a function. It is important to note that \(y\) and \(f(x)\) are used interchangeably. \(\begin{aligned} g ( \color{Cerulean}{- 2}\color{Black}{ )} & = ( \color{Cerulean}{- 2}\color{Black}{ )} ^ { 2 } = 4 \\ g ( \color{Cerulean}{\frac { 1 } { 2 }}\color{Black}{)} & = ( \color{Cerulean}{\frac { 1 } { 2 }} \color{Black}{)} ^ { 2 } = \frac { 1 } { 4 } \\ g (\color{Cerulean}{ x + h}\color{Black}{ )} & = ( \color{Cerulean}{x + h}\color{Black}{ )} ^ { 2 } = x ^ { 2 } + 2 x h + h ^ { 2 } \end{aligned}\), \(g (2) = 4,\: g ( \frac{1}{2} ) = \frac{1}{4} ,\: g (x + h) = x^{2} + 2xh + h^{2}\), At this point, it is important to note that, in general, \(f (x + h) f (x) + f (h)\). .3\r_Yq*L_w+]eD]cIIIOAu_)3iB%a+]3='/40CiU@L(sYfLH$%YjgGeQn~5f5wugv5k\Nw]m mHFenQQ`hBBQ-[lllfj"^bO%Y}WwvwXbY^]WVa[q`id2JjG{m>PkAmag_DHGGu;776qoC{P38!9-?|gK9w~B:Wt>^rUg9];}}_~imp}]/}.{^=}^?z8hc' There is exactly one output for every input. 33. g(x) = 2x + 1 Answer 34. g(x) = 5x 8 35. g(x) = 3x 2 Answer 36. g(x) = 8x + 2 37. g(x) = 3 x Answer 38. g(x) = 7 5x In the following exercises, evaluate the function. If asked to find \(x\) where \(f(x) = a\), we set the function equal to \(a\) and then solve for \(x\). In what years was the car valued at \($4,000\)? The domain of the graph of \(x=|y|+1\) consists of all x-values greater than or equal to \(1, [1,)\), and the range consists of all real numbers, \(=(,)\). On the other hand, an undefined function is the one whose points are outside the domain. How will the Relations and Functions Worksheet with Answer Key (PDF) help you?The learners will know if a given problem or situation is a relation or a function. This relation is not a function. You can get arithmetic support online by visiting websites such as Khan Academy or by downloading apps such as Photomath. If we consider each x-value to be the input that produces exactly one output, then we can use function notation16: The notation \(f(x)\) reads, f of x and should not be confused with multiplication. Domain: Range: Function: Domain: Range: 15 _ Function: Domain. (c) All functions are relations, but all relations are not functions. If any vertical line intersects the graph more than once, then the graph does not represent a function. Relations and Functions Worksheet (with Answer Key + PDF) 17The value or algebraic expression used as input when using function notation. In addition, since we can find a vertical line that intersects the graph more than once, we conclude that the graph is not a function. This notation is used as follows: \(\begin{array} { l } { f ( x )\:\: =\:\:\: | x | - 2 } \\ { \:\:\:\:\:\downarrow \quad\quad\quad \downarrow } \\ { f ( \color{Cerulean}{- 5}\color{Black}{ )} = | \color{Cerulean}{- 5}\color{Black}{ |} - 2 = 5 - 2 = 3 } \end{array}\). Ex 5. Given values for x in the domain, we can quickly calculate the corresponding values in the range. If any of the x values are repeated, but the values that correspond to them in the y-axis are different, then we are dealing with a relation rather than a function. Example: Decide whether the following relations are a function. The monthly income in dollars of a commissioned car salesperson is given by the function \(I(n) = 350n + 1,450\) where \(n\) represents the number of cars sold in the month. 1.
