Can somebody help me with this ?? :)
Alex777 [14]

Answer:

Your answer would be D, the equation is a function because it is a polynomial and all polynomials are functions.

Step-by-step explanation:

I like to remember that polynomials have no negative , fraction exponents and no division. In this case everything is positive so I knew it was a polynomial , and like the answer says all polynomials are functions !

Hope this helped

2. Graph the function y=x^2+2x-3 . Draw a chart to show at least three ordered pairs that are on the graph.
lidiya [134]
You'd have to draw a table of x and y values first to be able to graph.
Step 1: Pick any number for x. Let's pick 2.
Step 2: Plug in 2 into the equation: y = 2^2 + 2(2) - 3
Step 3: Solve for y: 4 + 4 - 3 = 5
Step 4: So the point (ordered pair) would be (x, y) ⇒ (2, 5). You can plot that on the graph.

Follow these steps 2 more times to get at least three ordered pairs.

Make sure you have enough points to know where the graph curves, then you can connect the dots and now there you have a graph and chart :)

Can someone please help me with these last 3 questions? <br> Offering 30 points (10 per question)
suter [353]
10. 4:5....added = 9
     4/9 (1800) = 7200/9 = 800 (red)
     5/9 (1800) = 9000/9 = 1000 (green)
     there were (1000 - 800) = 200 less red ones then green ones.

11. 7/4 = 21/r
      cross multiply
      (7)(r) = (4)(21)
      7r = 84
       r = 84/7
       r = 12....Rod has 12 stickers

12. 14/4 = 3.5 eggs per cup
      for 16 cups...16 * 3.5 = 56 eggs
