This is just notation so we can differentiated between multiple different functions instead of saying y=x + 4 we say f(x) = x + 4
 
This is because if we had two functions y = x + 4 and y = x - 6
 
it would get confusing to talk about them, so we use this notation to differentiate between theme easily by making f(x) = x + 4 and g(x) = x - 6
 
we can now talk about them easily and avoid confusion.

Answer:

function notation

Step-by-step explanation:

A function is a relation that assigns to each input number (x) exactly one output number. A function is notated a(x) =..., where a(x) indicates that the output value of the function, a, depends on x.

So, the notation "a(x) =..." corresponds to function notation.

Have a good day!!!
