The quadratic regression equation for the given data set is:
Option: C
.
Step-by-step explanation:
We are given the data set of values of the input value i.e. x and output value i.e. y in table form by:
Input (x) Output(y)
0 20
1 16
2 10
3 0
4 -7
5 -20
Now when we represent these data points on the scatter plot; we see that the quadratic equation that is obtained by plotting these points is:

The solution to the binomial expression by using Pascal's triangle is:
Pascal's triangle can be used to calculate the coefficients of the expansion of (a+b)ⁿ by taking the exponent (n) and adding the value of 1 to it. The coefficients will correspond with the line (n+1) of the triangle.
We can have the Pascal tree triangle expressed as follows:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1

From the given information:
The expansion of (3x-4y)^11 will correspond to line 11.
Using the general formula for the Pascal triangle:
The solution to the expansion of the binomial (3x-4y)^11 can be computed as:
