are piecewise functions always continuous?

A piecewise function is continuous on a given interval if the following conditions are met: it is defined throughout that interval, its constituent functions are continuous on the corresponding intervals (subdomains), there is no discontinuity at each endpoint of the subdomains within that interval.

A discrete function is a function with distinct and separate values. ... For example, a discrete function can equal 1 or 2 but not 1.5. A continuous function, on the other hand, is a function that can take on any number within a certain interval.

The absolute value function is continuous (i.e. it has no gaps). It is differentiable everywhere except at the point x = 0, where it makes a sharp turn as it crosses the y-axis. A cusp on the graph of a continuous function. At zero, the function is continuous but not differentiable.

Thus, the graph of f has a non-vertical tangent line at (x, f(x)). ... A function can fail to be differentiable at point if: 1. The function is not continuous at the point.

Differentiability and continuity The absolute value function is continuous (i.e. it has no gaps). It is differentiable everywhere except at the point x = 0, where it makes a sharp turn as it crosses the y-axis. A cusp on the graph of a continuous function.

if you have a set of x and y values. it would be a function if every x value is paired with exactly one y value every x value can only have one y. value. let's take a look at a couple examples and some ways to represent relations.

Rational functions are continuous for all real numbers except at those where the denominator is zero. If the denominator of a rational function f(x) is zero at x=a, then it contains some number of factors of (x - a).

A function is even if f(−x)=f(x) f ( - x ) = f ( x ) . Check if f(−x)=f(x) f ( - x ) = f ( x ) . Since 1x2=1x2 1 x 2 = 1 x 2 , the function is even.

In mathematics, a piecewise-defined function (also called a piecewise function or a hybrid function) is a function which is defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain (a sub-domain).

We use piecewise functions to describe situations in which a rule or relationship changes as the input value crosses certain “boundaries.” For example, we often encounter situations in business for which the cost per piece of a certain item is discounted once the number ordered exceeds a certain value.

Let's review. A discrete function is a function with distinct and separate values. A continuous function, on the other hand, is a function that can take on any number within a certain interval. Discrete functions have scatter plots as graphs and continuous functions have lines or curves as graphs.

A piecewise smooth curve is a curve C that can be broken into finitely many smooth pieces C1 C2, ..., Cn where the terminal point of one piece is the initial point of the next (Figure 13.2.9). For example, a curve formed by two or more sides of a rectangle or a polygon is piecewise smooth.

The absolute value function is continuous at 0. Computations of the two one-sided limits of the absolute value function at 0 are not difficult to complete. Since |x| = x for all x > 0, we find the following right hand limit. ... In fact, the absolute value function is continuous (on its entire domain R).

A function f is said to be continuous on an interval if it is continuous at each and every point in the interval. Continuity at an endpoint, if one exists, means f is continuous from the right (for the left endpoint) or continuous from the left (for the right endpoint).

When a function is differentiable it is also continuous. But a function can be continuous but not differentiable. For example the absolute value function is actually continuous (though not differentiable) at x=0.

Answer: Continuous if looking for exact age, discrete if going by number of years. If a data set is continuous, then the associated random variable could take on any value within the range. ... In such a case, Y , representing the age of an individual in years, could take on a finite number of values within our range.
