The graph of the piecewise function f(x) is shown. On a coordinate plane, a piecewise function has 2 lines that connect. The first line is horizontal to the y-axis at y = 4 and goes to (0, 4). The second line goes from (0, 4) through (4, 0).

What is the range of f(x)?

{f(x)| –∞ {f(x)| –∞ {f(x)|4 {f(x)|0≤f(x)<∞}

You and three friends will be going out to eat at your favorite restaurant! each of you will order three items of your choice. you will also need to leave a tip. if you split the bill evenly among all four of you, how much will each person need to contribute? locate a menu for your favorite restaurant and pick three items for yourself and each friend. list the restaurant name, items, and prices in a table like the one below. in the column labeled subtotal, determine the cost of each person’s order. the customary tip is 20% of the total bill. in the column labeled tip, calculate the amount of tip each person should leave. in the column labeled total bill, determine the total of each person’s order, including the tip. restaurant name: names item 1 price item 2 price item 3 price subtotal tip total bill your name friend #1 friend #2 friend #3 part 2: questions answer the following questions, showing all work: what is the total cost of the entire bill (all four meals), including tip? write an expression using fractions to show how to determine the amount that each person will pay. then calculate each person's contributions showing all steps in long division. if each person paid an equal amount, who would save the most money? explain your reasoning using at least two complete sentences.

Need this asap if anyone can i would be very grateful. if you could show workings that would really
