Find a polynomial equation that has zeros at x = −2, x = 0, x = 3 and x = 5

VashaNatasha [74]

If a polynomial "contains", in a multiplicative sense, a factor $(x-x_0)$ , then the polynomial has a zero at $x=x_0$ .

So, you polynomial must contain at least the following:

$(x-(-2)),\quad (x-0),\quad (x-3),\quad (x-5)$

If you multiply them all, you get

$x(x+2)(x-3)(x-5)=x^4 - 6 x^3 - x^2 + 30 x$

Now, if you want the polynomial to be zero only and exactly at the four points you've given, you can choose every polynomial that is a multiple (numerically speaking) of this one. For example, you can multiply it by 2, 3, or -14.

If you want the polynomial to be zero at least at the four points you've given, you can multiply the given polynomial by every other function.

2 1.800 54

3 3.333 74

4 2.283 62

5 4.533 85

6 2.883 55

R code :

1. You can directly access the "Faithful" data in R without importing the data. The dataset faithful is present in the R or you can load the datasets. or use install the datasets.load. package

If you have the data in a text file, make sure all the columns and rows are separated by commas

Step 1: open notepad

Step 2: enter data with no spaces but only commas

Step 3: save the file as ‘faithful.txt’ on your Desktop

# Get R help

?read.table

# Import the data

rain<-read.table("C:/Users/YOUR-NAME/Desktop/faithful.txt", header = TRUE,

sep = ",")

Check the data

data("faithful") #Loading Faithful data

head(faithful, 6) #Reading first 6 rows of the data
