i am working on this atm.
to solve you find the horizontal (x) intercepts.
so example graph A int is +3
then you find the equation where instead of f(x) etc, 0= the equation with the X value plugged in.
IE: 0=x^3-3x^2+x-3
would fit because when you simplify 0=0
0=3^3- 3(3^2)+3-3
0=27-27+3-3
0=0+0
0=0
it matches. so A would be the equation with f(x)
and continue in the same way
Answer:
<h3>C. 10</h3>
Step-by-step explanation:
let n1 be the degree of freedom of factor A
Let n2 be the degree of freedom of factor B
If there are 5 levels of factor A, then n1 = 5
If there are 7 levels of Factor B then n2 = 7
The interaction between the degrees of freedom is expressed using the formula;
df = (n1 - 1)+(n2 - 1)
df = n1 -1 + n2- 1
df = n1+n2 -2
Substitute n1 and n2 and get df
df = 5+7-2
df = 12-2
df = 10
Hence the interaction degree of freedom is 10
