Answer:
The exponential model is 
.
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
(1)
Where:
- Independent variable.
- Dependent variable.
- Coefficients.
If we know that 
and 
, then we get the following system of equations:
(2)
(3)
If we divide (3) by (2), we calculate the value of 
:
And by (2), we determine the value of 
:
The exponential model is .
Answer:
y = 4x+ 3
Step-by-step explanation:
Answer:
answer Z
Step-by-step explanation:
Look for a graph that contains the following zeros: x = 1, x = 2 , x= 3, following the info derived by the binomial factors that the function contains. Also look ate the fact that the function in question has for leading term positive 
, then this function must go towards plus infinity when x becomes large. This is the case for the graph option Z (the last graph of the group)
First one is 3/8>1/3
Second one is B
Third one is C
Fourth one is B
Exact form: x=7/6
Decimal form: x=1.16
Mixed number form: x=1 1/6
