The rectangular coordinate system1 consists of two real number lines that intersect at a right angle. +. Determine the domain and range of the following relation and state whether it is a function or not: \(\{(1, 4), (0, 7), (2, 3), (3, 3), (4, 2)\}\). Functions are compactly defined by an algebraic equation, such as \(f (x) = |x| 2\). stream Here we can see that the graph of \(y=|x|2\) has a domain consisting of all real numbers, \(=(,)\), and a range of all y-values greater than or equal to \(2, [2,)\). A Explanations 1. Relation. Here we separate the domain (x-values), and the range (y-values), and depict the correspondence between the values with arrows. \(g ( - 1 ) = 5 , g ( 0 ) = 3 , g \left( \frac { 3 } { 2 } \right) = 0\), 5. <>>> 120 students are studying in class 11 divided among four sections. If f (x) = 2x 3, then find [f (0) + (f)] / 2 and value of x when (a) f(x) = 0 (b) f(x)= x and f(x) = f(1-x). As pictured, the \(x\)-value \(3\) corresponds to more than one \(y\)-value.
