Answer: the answer is D
Step-by-step explanation: I got it right
Answer:
Yes.
The relation is a function because every element in the domain (the x's) is mapped to one element in the range (the y's).
Step-by-step explanation:
For a relation that is a set of points all you have to look for while igorning any duplicate points is that all of the x's are different. If there are any 2 (or more) x's that are the same, then it is not a function.
So there are no duplicate points.
For example the set {(1,5),(2,5)(1,5)} is really just {(1,5),(2,5)}.
Anyways the x's in the points are (in order from left to right):
1
-4
3
0
2
All of these are different, I did not list a value for x that was same anywhere in that list. So it is a function.
The relation is a function because there is no x that gets mapped to more than one y.
Answer:
110.4622 = 110 (as followers cannot be in decimals).
Step-by-step explanation:
Given, growth rate is 1% = 0.01.
and it is for every 12 hours.
now, f(x) = f(1 + r)^t. where f= 100 (initial followers)
r = 0.01.
t =10 (1 for every 12 hours. so, 5 days = 120 hours = 10 times)
⇒ f(x) = 100(1+0.01)¹⁰ = 110.4622 = 110 followers.

Answer:
Step-by-step explanation:
1. Find the slope:
7 -3/ 1 + 1 = 4/2 = 2 = m
2. Find b by plugging in the m and one of the points given into y = mx + b
7 = 2 ( 1 ) + b
7 = 2 + b
5 = b
3. Write the equation using the m and the b you just found
y =2 x + 5
