(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)

2x^2 + 3x + 4x - 9 = 2x^2 +7x -9

2x^2 + 7x - 9 - x^2 -7x = x^2 -9

The answer is : x^2 - 9

Which best describes the strength of a model with an r-value of 0.29
olchik [2.2K]
The <u>correct answer</u> is:

It is not a very strong fit.

Explanation:

The r-value, or correlation coefficient, tells us how closely our model fits the data.

The r-values range from -1 to 1.  -1 is a perfect fit of a decreasing model; 1 is a perfect fit of an increasing model.  0 is no fit at all.

Since our r-value is 0.29, this is much closer to 0 than it is to 1 or -1; this means it is not a very strong fit.
