Part of the graph representing an electrical signal is shown. the voltage rises steadily from an initial value (a) to a maximum value (b). it then drops instantly to the initial value (c) and repeats such that || and and are vertical. if a = (1, 1) and b = (4, 3), what is the equation of ?

a.
-3y − 2x = 5
b.
3y − 2x = 5
c.
3y − 2x = -5
d.
3y + 2x = 5

a=r

d=q

c=p

b=s

hope this !

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!
