Which graph represents a function? which statement explains why your graph from question 4 is a function? question 5 options: each y value pairs to any x value. it is the graph of a linear equation. each x value pairs to one and only one y value. the solutions to the equation can be written as ordered pairs.

Part 1:

The final graph with upward parabola represent a function because only this curve passes the Vertical Line Test.

Part 2:

Each x value pairs to one and only one y value.

To check whether a graph is function or not we use Vertical Line Test which draws a vertical line. A function must have one output y for each unique value of x.

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

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!
