Violent Crimes The function V(t) = 5.062 - 87.3t + 1761.1
models the number V (in thousands) of violent crimes com-
mitted in the United States t years after 1995, based on data
obtained from the Federal Bureau of Investigation. Sot = 0
represents 1995,
= 1 represents 1996, and so on.
(a) Determine the year in which the fewest violent crimes
were committed.
(b) Approximately how many violent crimes were commit-
ted during this year?
(c) Using a graphing utility, graph V = V(t). Were the num-
ber of violent crimes increasing or decreasing during the
years 1995 to 2003?

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!
