3 is positive because it is more than 0. Anything more than zero is positive.
Answer:
Step-by-step explanation:
See the attached graph.
The points (0,3) and (1,1) are on the graph of the exponential function.
Let the function be 
....... (1)
Now, satisfying the point (0,3) we get from the equation (1),
Therefore, the initial value of the function is a = 3
Hence, the equation becomes 
......... (2)
Now, satisfying the point (1,1) we get from equation (2)
⇒ b = 1/3
So, the final equation becomes (Answer)
No 1+1 does not equal fish.....I thought so too until I looked it up
Function rule: a = 20w + 115
Slope: 20
Initial value: 115
------------------------------------------
We start with $115 in the account. This is the initial value. Each week we add on $20.
So we add $20 for 1 week
We add 2*20 = $40 for 2 weeks
We add 3*20 = $60 for 3 weeks
etc etc
In general, we add 20*w dollars for w weeks onto 115 to get a = 20w+115
The slope is 20 because this is the rate of change, ie how fast the account grows. It grows 20 dollars per week.
y=2x-0.5
Step-by-step explanation:
Given the expression of Δy in terms of Δx as;
Δy=4/2 Δx
Given y=2.5 and x =1.5 then substituting in the equation above will give;
y-2.5=2(x-1.5)
y-2.5=2x-3
y=2x-3+2.5
y=2x-0.5
