What is the exponential function modeled by the following table?
steposvetlana [31]

Answer:

f(x)=9^{x-1}

Step-by-step explanation:

The general form of the exponential function is,

y=ab^x

The points on the graph will be,

(2,9),(3,27),(4,81)

Putting the points in the function,

9=ab^2  -----------------------------------1

27=ab^3  ---------------------------------2

Dividing equation 2 by equation 1,

\Rightarrow \dfrac{27}{3}=\dfrac{ab^3}{ab^2}

\Rightarrow 9=\dfrac{b^3}{b^2}

\Rightarrow b=9

Putting the value of b in equation 1,

\Rightarrow a(9)^2=9

\Rightarrow a=\dfrac{9}{9^2}

\Rightarrow a=\dfrac{1}{9}

Putting all the values,

\Rightarrow y=\dfrac{1}{9}\cdot 9^x

\Rightarrow y=9^{x-1}

The equation of the line in this graph is<br>y= ____ x+____ .<br>​
Alexxx [7]
The equation of the line in this graph is y = 3/2x + 3.

Explanation:

In slope intercept form equations, the initial value is where everything begins. In this equation, that would be at the point (0,3). From there, because it is going up toward the right side, there is a positive slope. The formula for slope is rise over run, so to get our slope, we have to go up 3 units and over 2 units.
