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
