I've been stuck on this for awhile, and I need some genuine help.

Answer:
y = 130/3 + 5
Step-by-step explanation:
(0,5) (1,15) (2,45) (3,135)
Answer:
Step-by-step explanation:
We can express an exponential equation as: y=ar^x. Using points (1, 15) and (2, 45).
45/15=(ar^2)/(ar^1)
3=r, now using (1, 15) we can find the value of a
15=a(3^1), so a=5 then the equation is
y=5(3^x)
