Study Notes
Inequalities and Functions
-
The total amount of 5 Peso and 10 Peso coins in Kyle's bag can be mathematically represented as 5x + 10y > 300, where x and y are the number of coins.
-
The sum of 20-peso bills (t) and 50-peso bills (f) that Vienne has can be mathematically represented as 20t + 50f > 500.
-
The cost of a tray of medium-sized eggs, if Euricka paid at least Php 550 for a tray of extra-large sized eggs and 2 trays of medium-sized eggs, is Php 173, since 550 - 204 = 346, and 346 ÷ 2 = 173.
Domain and Range
-
In the context of relations and functions, the term 'domain' refers to the set of input values or x-values.
-
The term 'range' refers to the set of output values or y-values.
-
A relation in terms of sets of ordered pairs is a collection of points on a coordinate plane, where each point is represented as an ordered pair (x, y).
Function Types
-
A function involves no two pairs having the same first element (x-values), meaning that each input value has a unique output value.
-
A relation where multiple x-values correspond to a single y-value is not a function.
Linear Inequalities
-
The shaded area in the graph of a linear inequality represents the solution to the inequality.
-
A system of linear inequalities is considered to have an open or unbounded solution when the common shaded region is not bounded by a specific point.
-
When a system of linear inequalities forms a common shaded region bounded by 3 lines, the solution type is a polygon.
Function Evaluations
-
The correct evaluation of f(2) if f(x) = x^2 - 3x + 2 is f(2) = 2^2 - 3(2) + 2 = 0.
-
For the function h(x) = 5x - 3, the value of x for which h(x) = 12 is x = 3, since 5x - 3 = 12, and x = (12 + 3) ÷ 5 = 3.
