The range of a function is the set of all values that it can take when its independent variable takes values on the domain.
On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.
In the case of the given equation:
The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:
If the range of the original function is the set given by the number {
Hey!!
here is your answer >>>
the total money is 270 , it is shared among three people .
let's take the amount of Polly as X
then, the amount of Andy would be 2x
then, the amount of Phoebe would be 6x
the sum of 6x,2x and x is 270!.
let's add them up,
9x = 270
x = 30!.
Polly = £30
Andy= £60
Phoebe = £180
Hope my answer helps!
Change the percent to decimal
4%= .04
.04x = 56
solve for x
so x = 1400

Answer:
y = 3/5 x - 2
Step-by-step explanation:
To find the equation of the line, calculate the slope using two points. With the slope and one point, substitute them into the point slope form and simplify as needed.
Use the points (5,1) and (0, -2) since -2 is the y-intercept.
Slope = 
y - -2 = 3/5 (x - 0)
y + 2 = 3/5(x)
y = 3/5 x - 2
