ANSWER
The standard form is:
EXPLANATION
The given line passes through (4,10)and (6,11).
The slope of this line is
The equation is given by the formula,
We plug in the first point and the slope to get.
The standard form is
The exponential function that represents the table is
An exponential function is any function that has its constant raised to the power of an argument.
An exponential function is represented as:
Where:
- a represents the initial value
- b represents the rate
From the table we have the following ordered pair
(x,y) = {(0,2) (1,8)}
So, we have:
Also, we have:
Divide both sides by 2
So, we have:
Hence, the exponential function is:
