2a^2b+2ab
This is the answer (at least I think so)
15 more than half a number would be 1/2x (or whichever variable) plus 15
Answer:
an = 5 + 2n
Step-by-step explanation:
Each time it increases by the same amount (2), so this is an arithmetic sequence:
an = a₁ + d (n - 1)
Given a₁ = 7 and d = 2:
an = 7 + 2 (n - 1)
an = 7 + 2n - 2
an = 5 + 2n
Check our answer:
n=1: a₁ = 5 + 2(1) = 7
n=2: a₂ = 5 + 2(2) = 9
n=3: a₃ = 5 + 2(3) = 11
n=4: a₄ = 5 + 2(4) = 13
<u>Answer:</u>
The correct answer option is f(x) = 3^(x+3).
<u>Step-by-step explanation:</u>
We are to determine whether which of the given answer options represent the given graph.
A graph which has a similar shape like that of the given graph here (big on the left and crawling along the x-axis on the right) represents the exponential growth or decay.
Therefore, the only correct option we have here is f(x) = 3^(x+3).
