H(x)= 4/x-5 Determine for each x-value whether it is in the domain of h or not.
1 answer:
Answer:
x = 5 is not in the domain
Step-by-step explanation:
Given
f(x) =
The denominator cannot equal zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be, that is
x - 5 = 0 ⇒ x = 5 ← excluded value
Thus the domain is all real except x ≠ 5

Answer:
Yes, 2 and 0 are the zeroes.
Step-by-step explanation:
Given polynomial: x²-2x
p(2)= 2²-2(2)
= 4-4
= 0
p(0)= 0² -2(0)
= 0-0
= 0
