Gerald graphs the function f(x) = (x – 3)2 – 1. which statements are true about the graph? check all that apply.

the domain is {x| x ≥ 3}.
the range is {y| y ≥ –1}.
the function decreases over the interval (–∞, 3).
the function increases over the interval (–1, ∞).
the axis of symmetry is x = –1.
the vertex is (3, –1).

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
