Question

f(x)=(4x^2)/(x^2-1) Find the points of intersection, if any, of the graphs of y = f (x) and y = 4.

Answer 1

You got equations
y = f (x)
y = (4x^2)/(x^2-1)
and
y = 4
you can solve them simultaneously

Answer 2

thank you. but i can't solve this

Answer 3

Try graphing ,

Answer 4

Set them equal to each other

\[\large 4 = \frac {(4x^2)}{(x^2-1)}\]

Try solving for x, if possible.

Answer 5

Try multiplying both sides by (x^2-1)

Answer 6

Seemed to be no solution or no intersection

Answer 7

Here's the graph

Answer 8

\[\large 4(x^2-1) =4x^2\]

Answer 9

become 4x^2-4=4x^2
-4x^2+4x^2-4=0
then -4=0

Answer 10

Correct, which is not true, so no solution.

Answer 11

i soleve taht . but i ask not another solve

Answer 12

thank you sam and agent0smaith
