Answer:

  f(x) = -1.18056x² +9.55556x -12.4604

Step-by-step explanation:

As required by the problem statement, technology was used to find the polynomial function that passes through the given points. The coefficients shown above are rounded to 6 significant figures. The exact coefficients appear to be ...

Answer:

The required equation is f(x)=-1.1806x^2+9.5556x-12.46

Step-by-step explanation:

Given : The function for the graph that passes through the points (2.1,2.4), (4.3,6.8), and (6.1,1.9).

To find : Determine the function?

Solution :

First we plot the points with the help of graphing tool.

When we add trend-line in the points it will given you the equation of best fit of the points.

Using Regression calculator,

The equation is given as y=-1.1806x^2+9.5556x-12.46

and correlation coefficient is R^2=1 showing the best fit line.

Refer the attached figure below.

The required equation is f(x)=-1.1806x^2+9.5556x-12.46

3. For the polynomial: ()=−2(+19)3(−14)(+3)2, do the following:A. Create a table of values that have the x-intercepts of p(x) in
Pepsi [2]

Part A. We are given the following polynomial:

\mleft(\mright)=-2\mleft(+19\mright)^3\mleft(-14\mright)\mleft(+3\mright)^2

This is a polynomial of the form:

p=k(x-a)^b(x-c)^d\ldots(x-e)^f

The x-intercepts are the numbers that make the polynomial zero, that is:

\begin{gathered} p=0 \\ (x-a)^b(x-c)^d\ldots(x-e)^f=0 \end{gathered}

The values of x are then found by setting each factor to zero:

\begin{gathered} (x-a)=0 \\ (x-c)=0 \\ \text{.} \\ \text{.} \\ (x-e)=0 \end{gathered}

Therefore, this values are:

\begin{gathered} x=a \\ x=c \\ \text{.} \\ \text{.} \\ x=e \end{gathered}

In this case, the x-intercepts are:

\begin{gathered} x=-19 \\ x=14 \\ x=-3 \end{gathered}

The multiplicity are the exponents of the factor where we got the x-intercept, therefore, the multiplicities are:

Part B. The degree of a polynomial is the sum of its multiplicities, therefore, the degree in this case is:

\begin{gathered} n=3+1+2 \\ n=6 \end{gathered}

To determine the end behavior of the polynomial we need to know the sign of the leading coefficient that is, the sign of the coefficient of the term with the highest power. In this case, the leading coefficient is -2, since the degree of the polynomial is an even number this means that both ends are down. If the leading coefficient were a positive number then both ends would go up. In the case that the leading coefficient was positive and the degree and odd number then the left end would be down and the right end would be up, and if the leading coefficient were a negative number and the degree an odd number then the left end would be up and the right end would be down.

Part C. A sketch of the graph is the following:

If the multiplicity is an odd number the graph will cross the x-axis at that x-intercept and if the multiplicity is an even number it will tangent to the x-axis at that x-intercept.

Define powers provide an example of power with an exponent of 2
shtirl [24]
Well not sure what you are asking, but If it is what I think it is, it would go like this: 
          2 
(9^2)

Then the answer should be 

9^4 since we multiply the exponents. 

If you mean this...

3^2....It would be same as 3 x 3 which we should know is equal to nine. 

Hope I helped! (Be sure to thank me!)
