Question

Keira created color panels for a wall using a mix of only red and blue paints. She plotted the quantities of red and blue paints used for each mix and connected them using a line segment as shown in the graph below.

Answer 1

Which statement best describes the domain of the function represented in the graph?

3 ≤ x ≤ 12 or x is between 3 and 12, inclusive

3 ≤ x ≤ 7 or x is between 3 and 7, inclusive

2 ≤ x ≤ 12 or x is between 2 and 12, inclusive

2 ≤ x ≤ 7 or x is between 2 and 7, inclusive

Answer 7

Well, what's value of x at the left end of the line? What is the value of x at the right end of the line?

Answer 8

3 at the left 7 at the right...

Answer 9

the b option should be correct
method of determining the domain is
you drop a line perpendicular from the end points of the graph, and the point at which it cuts the x axis gives you the domain

Answer 10

then 3 <= x <= 7 is your domain.

Answer 11

all the points on the line fall in that range.

Answer 12

Oh okay thanks! :) Thank you both :)

Answer 13

uh, I shouldn't say "range" I suppose :-)

Answer 14

lol @whpalmer4 i get it! XD

Answer 15

what is the range of this function?

Answer 16

also ,

if there is a uncolored circle then it means don`t include the point, else include it

Answer 17

between 2 and 12 @whpalmer4 ... ?

Answer 18

yes! and you'll notice the dastardly problem author threw that in as an answer choice to trap the unwary...

Answer 19

lol thanks again :) @whpalmer4

Answer 20
