Description

Example 6: Write a function equation of the form f(x) based on the Function Machine that multiplies the input by itself (squares it). The input is 5, and the output is 25.

Substitute the input with x. Since the machine squares the input, the function equation is f(x) = x2.

When students are exposed to various worked-out examples, they develop a deeper understanding of mathematical concepts by seeing patterns, variations, and applications of the rules in different contexts. Each example provides a fresh perspective and reinforces the core concept.

Teacher’s Script: Let's analyze this example together. Notice how the input changes, and observe the mathematical operation applied by the function rule. Can you predict the output for a new input based on this pattern?
