Question

How do you rewrite a equation in function form?

Answer 1

function form means one variable is expressed as a function of another (or several other) variable(s).

the simplest example is the equation of a line.
standard form is something like
ax + by = c

the standard Cartesian coordinate system would have x as the independent variable and y as the dependent. so we would rearrange it as
y = -ax/b + c/b
here y is a function of x. to mathematically write "y is a function of x" we write:
y = f(x)
hence we can write the line's equation in "functional form":
f(x) = -ax/b + c/b

Answer 2

function form usually means isolating the variable of interest. if you want a function of x, you rewrite the equation so all the x's are on one side, like y=x+3. then you can say that y is a function of x, or y=f(x)=x+3, or just f(x)=x+3.

Answer 3

For increasing cubic binomials the final formulation is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^a million + 3*a^a million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^a million + 3*x^a million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

Answer 4

First, you need the equation.

Then you use function notation

************************** f(x) = y *******************************

here x is the independent variable and y is the dependent variable.

Answer 5

y = 3x - 2 becomes
f(x) = 3x - 2

4x - 2y = 4 becomes
-2y = -4x + 4
y = 2x - 2
f(x) = 2x - 2

AN equation, not a.

Answer 6

f(x)=
