Answer:

No

Step-by-step explanation:

An equation written in function form begins with f(x)

[or another letter like g(x) or h(x).] It's read "f of x" or "f at x".

f(x) replaces "y" in an equation.

If you want to write 15x + y = 20 in function form, isolate "y" then replace it with f(x).

15x + y = 20

y = 20 - 15x

f(x) = 20 - 15x
