We can create functions that behave differently based on the input (x) value. A function made up of 3 pieces. when x is less than 2, it gives x2,.

HSF.LE.A.2 Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include …

A function is continuous when its graph is a single unbroken curve ... that you could draw without lifting your pen from the paper.

This is the Absolute Value Function: f (x) = x. It is also sometimes written: abs (x). This is its graph: f (x) = x.

☐ Understand what it means to say a function is differentiable, and how to choose an appropriate domain. Know that a differentiable function is continuous, but a continuous function is not …

Illustrated definition of Spline: A function made up of polynomials that each have a specific interval. In other words a piecewise polynomial...

What is a Function? A function relates an input to an output. It is like a machine that has an input and an output. And the output is related somehow to the input.

To evaluate a function is to: Replace (substitute) any variable with its given number or expression. Like in this example:

Sometimes we can't work something out directly ... but we can see what it should be as we get closer and closer!
