Applying for a job is more than just filling out an application. A function is a relation in which each possible input value leads to exactly one output value. Relation. Mathematics is a way of dealing with tasks that involves numbers and equations. Find \(x\) where \(g (x) = 5, g (x) = 4\), and \(g (x) = 4\). There is exactly one output for every input. 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. Here we are asked to find the x-value given a particular y-value. Given \(f ( x ) = \sqrt { 2 x + 4 }\), find \(f (2), f (0)\), and \(f \left( \frac { 1 } { 2 } a ^ { 2 } - 2 \right)\). a. b.
