Answer:
Step-by-step explanation:
I used the following points.
x y
-10 -1
-5 -1
-1 0
0 1
1 3
2 7
3 15
From which I think the graph turns out to be y = 2^(x + 1) - 1
-6 2
0 5
1 8
2 14
From which I get y = 3*2^x + 2
You may say to me that's all well and good, but how did you do it? You have to take a few wild guesses. It also helps to know where the question came from. What were you studying when the graphs were assigned?
I don't think there is a magic bullet for figuring these out. You just have to keep on trying until you get it.
One thing is certain. You should work on the y intercept (5) and the distance above or below the x axis. The distance above the x axis is 2 which means that c = 2.
y = a*b^x + c
c is the constant above or below the x axis. You need only read the graph to get the result. a is the hardest to find, but it will be just slightly easier when you let x = 0.
a + c = 5 Since c = 2 a must be 3
