HELP PLZ WILL GIVE IF WORK AND ANSWER IS CORRECT Q: Find the x-coordinates of any relative extrema and inflection point(s) for the function f(x) = . You must justify your answer using an analysis of f '(x) and f "(x).

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

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.

step-by-step explanation:
