Which of the following describes the end behavior over the domain of the square root function graphed above?
a. as x decreases in value, f(x) decreases in value.
as x increases in value, f(x) increases in value.
b. as x decreases in value, f(x) increases in value.
as x increases in value, f(x) decreases in value.
c. as x decreases in value, f(x) increases in value.
as x increases in value, f(x) increases in value.
d. as x decreases in value, f(x) decreases in value.
as x increases in value, f(x) decreases in value.

A.

Step-by-step explanation:

As x decreases f(x) decreases.

As x increases f(x) increases.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
