Question

Find Y if f(x)=g(x),please help me to answer this problem.

Answer 1

Explanation:

( x , y )

( 0 , - 4 )

( 1 , - 1.5 )

`y_(1)` = - 4

`y_(2)` = - 1.5

Answer 2

If f(x) = g(x)

Then :

(x-4)/(x²+1) = (x² - 4) / (x²+ 1)

We can simplify on both sides by x² + 1 :

x - 4 = x² - 4

x = x²

x - x² = 0

x(1-x) = 0

So either x = 0, or x = 1

S = {0,1}

Good Luck
