99! test on relations and functions1. find the inverse of the function f(x) = 3x – 7, show all work! 2. use a mapping diagram to represent the relation {(2,4), (3,4), (4,4), (5,4)}, state if the relation is a function.3. draw a graph on the coordinate plan that represents a function. explain your reasoning! for questions 4-8, use the above graph.4. evaluate f(2).5. list all x-intercepts.6. evaluate f(-0.7)? 7. evaluate f(1.9)? 8. it the graph a function? explain your reasoning.9. if f(x) = 3x-6, what is f(-9)? 10. if f(x) = 42 + 3, what is f(-2)?

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:

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
