Question

15x + y = 20 in function form

Answer 1

To convert the equation 15x + y = 20 to function form, isolate y by subtracting 15x from both sides, resulting in y = 20 - 15x or f(x) = 20 - 15x.

Step-by-step explanation:

To write the equation 15x + y = 20 in function form, we need to solve for y in terms of x. Here is the step-by-step process:

1. Start with the original equation: 15x + y = 20.
2. Subtract 15x from both sides of the equation to isolate the y variable: y = 20 - 15x.

Now the equation is in function form, with y expressed as a function of x, which is often written as y = f(x). So, the function form is f(x) = 20 - 15x.

Answer 2

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
