What is a Function? - Definition & Examples

Leia is trying to create a machine representing the function $f(x) = 2x+10$. Given an input $x$, the machine should output $2x+10$ in the end through a process.

However, she is stranded on an island with only two kinds of machine parts:

• $\times 2$ parts, which will double what they're given; and
• $+5$ parts, which will add $5$ to what they're given.

Luckily, Leia can piece these parts together in any order she wants.
