Sal recorded the number of crackers in each snack-sized package he opened. A number line goes from 5 to 15. The whiskers range from 7 to 15, and the box ranges from 7 to 10. A line divides the box at 9.

Which statement must be true according to the box plot?

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

the answer is a. q=6,r=6√2

step-by-step explanation:
