Question

Find the provience of f(x) = x² + 3x + 5/
xc² - 5x+4​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

(−∞,−3)∪(−3,1)∪(4,∞)

g

f

​

(x)=  

x+3

x  

2

−5x+4

​

 

​

 

For  

g

f

​

 to be defined,

⇒x  

2

−5x+4≥0

(x−4)(x−1)≥0

⇒x∈(−∞,1]∪[4,∞)

Also x+3



=0

⇒x



=−3

So x∈(−∞,−3)∪(−3,1)∪(4,∞)
