Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. Understand interval notation bett
To write in interval notation, use parentheses for opened ends and square brackets for closed ends. The first and last values within the interval are then written within and separated by a comma.What is an Interval? Similar to its English meaning, in Math, an interval can be thought of as...

The length of an interval with endpoints a and b with a < b is b - a.Converting an inequality to interval notationExpress each inequality in interval notation. Examples Inequality Interval notation -6 ≤ x < 1 [-6, 1) x > 20 (20, ∞) x ≥ -1 or x < -4 (-∞, -4) U [-...
Domain of Quadratic FunctionA quadratic function is a polynomial function that is defined for all real values of x. So, the domain of a quadratic function is the set of real numbers, that is, R. In interval notation, the domain of any quadratic function is (-∞, ∞)....
The last form of solution notation is actually more of an illustration. You may be directed to "graph" the solution. This means that you would draw the number line, and then highlight the portion that is included in the solution to the inequality. First, you would mark off the edge of...
The graph of this function is called the Pareto frontier. In order to measure how bad a vaccination strategy can be, we will also be interested in maximizing the effective reproduction number given a certain quantity of vaccine: Maximise: the effective reproduction number Re subject to: a given...

A function takes an input (x) and produces a single output (y) for each x-value. Functions also pass thevertical line test; if you draw a vertical line through the graph of a function, it never intersect the graph more than once. ...
