Question

Change from typical notation to function notation

y = 5x - 2

Answer 1

Let's see

`\\ \rm\rightarrowtail y=5x-2`

• . Function notation.

`\\ \rm\rightarrowtail g(x)=5x-2`

Some test

• g(2)=5(2)-2=8

Answer 2

f(x) = 5x - 2

Explanation:

To change from typical notation to function notation, simply replace y with f(x). Remember to ensure the variable you put in the brackets is the same as the variable in the equation.

So y = 5x - 2 becomes f(x) = 5x - 2 (since the variable is x)

And y = 5a - 2 becomes f(a) = 5a - 2 (since the variable is a)

The typical letter to use is f, but we can use other letters.

Other common function notations are g(x) and h(x).
