Consider the quadratic function.
f(p) = p2 – 8p – 5
what are the values of the coefficients and the constant in the function?
a = –1, b = –8, c = –5
a = 1, b = –5, c = –8
a = 1, b = –8, c = –5
a = –1, b = –5, c = 8

does anybody know

answer: the equation matches the regression

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
