How do you rewrite things in function form? Please provide an example..?
just change y to f(x)
y=2x
f(x)=2x
Here's a sample problem:
5x+6y=-12
How would you write this in function form?
first put it in slope intercept form
5x+6y=-12
6y=-5x-12
y=(-5/6)x-2
so:
f(x)=(-5/6)x-2
Okay thanks,(:
To rewrite something in function form, you need to express it in terms of a mathematical function. This involves converting any given information or expression into a function notation consisting of an input and an output.
Let's consider an example:
Let's say you have the equation of a line expressed in standard form: 2x + 3y = 6, and you want to rewrite it in function form.
1. Begin by solving the equation for y, which means isolating y on one side of the equation.
2x + 3y = 6
Subtract 2x from both sides:
3y = -2x + 6
2. Divide both sides of the equation by 3 to solve for y:
y = (-2/3)x + 2
3. Now, we can rewrite it in function form by replacing y with f(x) or any other function notation. Let's use f(x):
f(x) = (-2/3)x + 2
Now, the equation of the line is expressed in function form. This means that for any given value of x, you can plug it into the function f(x) and determine the corresponding value of y on the line.
