A function's inputs do not repeat. This means that any point with the x-value not repeated with the other points can be added to ensure that it continues as a function.

In this scenario:

{x| x ≠ -7, 4, 0, -2}

A point that does not have the x-value of -7, 0, 4, and -2 could be added to the relation to ensure it continues to be a function.

Hope this helps.

Find an equation equivalent to r= 1 + 2 sin thete in rectangular coordinates

noname [10]

Answer:

x^2+y^2=(x^2+y^2-2y)^2

Step-by-step explanation:

Here we are given that

r=1+2sin

we know that the polar cordinates are represented as

x=rsin

y=rcos

Also squaring both and adding them gives you ,

Hence

also r=1+2sin

1+2sin =

Also ,

r = r=1+2sin

also sin =

Hence replacing sin we get
