1) Which quadratic regression equation models the following data points? (1, 6), (3, 8), (7,0)
a. f(x) = -0.5x2 + 3x + 3.5
c. f(x) = 0.5x2 + 3x + 3.5
b. f(x) = -0.5(x − 3)(x – 3.5)
d. f(x) = -0.5(x + 3)(x +3.5)

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.
