Answer:

x = -2a/(y - 2).

Step-by-step explanation:

y= 2(x-a)/x

Cross multiply:

xy = 2(x - a)

xy = 2x - 2a

xy - 2x = -2a

x(y - 2) = -2a

x = -2a/(y - 2).

Answer:

y = 2(x-a)/x

xy = 2x-2a

xy-2x = -2a

x(y-2) = -2a

x = (-2a)/(y-2)

Give the domain and range.
alexgriva [62]

Answer:

c. domain: {-2, 0, 2}, range: {-1, 1, 3}

Step-by-step explanation:

Given:

There are three points on the graph.

Locate the x and y values of the points on the graph.

The points are (-2,-1),(0,1),\textrm{ and }(2,3)

Domain is the set of all possible x values. Here, the x values are -2, 0 and 2.

So, domain is: {-2, 0, 2}.

Range is set of all possible y values. Here, the y values are -1, 1 and 3.

So, range is: {-1, 1, 3}
