Answer:
Undefined at x = 2 and x = -2
Step-by-step explanation:
(5x²+x+11)/(x²-4)
Function becomes undefined when the denominator goes to zero.
x² - 4 = 0
x = 2, -2
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
cot A = 
, tanA = 
, cscA = 
, secA = 
Consider the right side
= 
= 
= 
× sinAcosA ( cancel sinAcosA )
= cos²A - sin²A
= cos2A
= left side ⇒ verified
4. It has exactly 2 parallel sides.
