Answer:
A) The expression is given by 
.
B) The remaining butterflies after Ellen captures 7 butterflies is 41.
Step-by-step explanation:
A) As the number of butterflies keeps doubling every minute so the repeating number is 2 thus we use the term 
where n given the number of minutes passed.
Initially there were 3 butterflies on the screen so we multiply the term with the initial number of butterflies 
. So the expression becomes:
B) After 4 minutes Ellen captures 7 butterflies from the total, So we subtract the term 7 from the number of butterflies we calculated through the expression.
So, after 4 minutes
As Ellen has captured 7 butterflies, So:
Answer:
y = 3x + 6
Step-by-step explanation:
The domain is you x values. You need to substitute the x values into both functions to see which one produces the plots on the graph.
<h3>y = 2x + 4</h3>
when x = -3, y = 2(-3) + 4 = -6 + 4 = -2
when x = -2, y = 2(-2) + 4 = = -4 + 4 = 0
when x = -1, y = 2(-1) + 4 = = -2 + 4 = 2
when x = -0, y = 2(0) + 4 = 0 + 4 = 4
<h3>y = 3x + 6</h3>
when x = -3, y = 3(-3) + 6 = -9 + 6 = -3
when x = -2, y = 3(-2) + 6 = = -6 + 6 = 0
when x = -1, y = 3(-1) + 6 = = -3 + 6 = 3
when x = -0, y = 3(0) + 6 = 0 + 6 = 6
The points on the graph are (-3, -3), (-2, 0), (-1, 3) and (0, 6)
This is same as the results from the function y = 3x + 6
