Give the domain and range. On a coordinate plane, points are at (negative 2, negative 1), (0, 1), (2, 3).
a.
domain: {2, 0, 2}, range: {1, 1, 3}
b.
domain: {–1, 1, 3}, range: {–2, 0, 2}
c.
domain: {–2, 0, 2}, range: {–1, 1, 3}
d.
domain: {1, 1, 3}, range: {2, 0, 2}

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

2       0.96

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.

have a nice day!
