1) not function because 6 number repeat in domain
2) Function
For 3 and 4 I guess it's
3) Function
4)not function
If any number repeat twice in the domain that will be not a function
Answer:
B
Step-by-step explanation:
To determine if x = 6 is a solution, substitute x = 6 into the left side of the equation and if equal to the right side then it is a solution.
2(6) - 5 = 12 - 5 = 7 ≠ 1
Then x = 6 is not a solution of the equation since a false statement results after replacing x with 6 (B)
9 hour is the answer hope it helps
f(x) = sqrt(x)
f(17) = sqrt(17)
it is close to sqrt(16)=4
so to the nearest integer
f(17) = 4
30 x 0.05 = $1.5 is the answer
