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.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
