Answer:
f(x) = 5x - 2
Step-by-step 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).
