Which of the following is true of the fundamentals of regression analysis? A fundamental basis of regression analysis is the assumption of a circular relationship between the independent and dependent variables. The differences between actual and predicted values of the dependent variable are known as regression coefficients and are represented by b. Any point that falls on the line of a regression analysis is the result of unexplained variance. The regression coefficient is calculated by squaring errors of each dependent variable. Regression uses an estimation procedure called ordinary least squares that guarantees the line it estimates will be the best fitting line.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
