Consider the two functions described below.

function 1 is represented by the graph below. it shows the distance carl travels y in x hours at a constant speed.

function 2 represents the following scenario: the equation y = 25x gives the distance y sheila travels in x hours.

which is a correct description of how to compare the rates of change in each scenario?
a. compare the change in x over the change in y for each function.
b. compare the change in y over the change in x for each function.
c. compare the values at which the graphs cross the x-axis.
d. compare the values at which the graphs cross the y-axis.

B.Compare the change in y over the change in x for each function.

Step-by-step explanation:

Find the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

Change in y\Change in x

y = 40x

By the definition of slope, you have your answer.

I am joyous to assist you anytime.

well the answer to that is xoxoxo

step-by-step explanation:

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!
