Answer:
y = 12
Step-by-step explanation:
y = 3x2+6
= 6+6
= 12
y = 12
Add powers of 3.
1 + 3 = 4
4 + 9 = 13 = 4 + 3^2
13 + 27 = 40 = 13 + 3^3
40 + 81 = 121 = 40 + 3^4
Now you need to add 3^5 to 121.
121 + 3^5 = 121 + 243 = 364
First we multiply 7 and 0.15 to see how many he lost. We get 1.50 so now we know he lost 1.50 of his collection. we add 5.55 and 1.50 and get 7.05 we divide 7.05 by 0.15 47.

Answer:
First graph
Step-by-step explanation:
The y-intercept of f(x)=2(3)^x is found by letting x = 0: f(0) = 2(3)^0 = 2.
Thus, we can immediately eliminate the 2nd and 4th answer graphs.
Next, determine whether (1, 6) from the first graph satisfies f(x)=2(3)^x:
2(3)^1 = 2(3) = 6. Yes. So the first graph is the correct one.
