Which equation models the rational function shown in the
graph?
f(x) = 2(x+2)/x-2
f(x) = x-2/x+2
flv) = 2(x-2)
f(x) = x+2/x-2

f(x)=

Step-by-step explanation:

We are given that a graph.

We have to find the equation which models the rational function shown in the graph.

From given graph we can see that

At x=2, the function in the graph is approaches to infinity.

It means function is not defined at x=2

We know that a rational function is undefined when denominator is equal to zero.

f(x)=

x-2=0

x=2

It means function is not defined at x=2

y-intercept:y=-2

The function is passing through the point (1,-6).

When substitute x=1

Therefore,Option 2 is not correct because function is not defined at x=-2

Hence, option 1 is true.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
