First you must distribute the 2x to the numbers inside the parentheses
(2x * x) + (2x * -1) = 3
- 2x = 3
To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides
- 2x - 3 = 0
Use the quadratic equation to solve this (image of the quadratic equation is below)
Remember that quadratic functions are set up like so:
That means that in this equation...
a = 2
b = -2
c = -3
^^^Plug these numbers into the quadratic equation and solve...
Keep in mind that +/- is ±

I don't know what the graph is counting by but here is an explanation:
Domain: (x value furthest left) ≤ x ≤ (x value furthest right)
Range: (y value furthest up) ≤ y ≤ (y value furthest down)
If n=4 then plug it into the equation.
4-1
3
so your answer is 3
Answer:
3rd
Step-by-step explanation:
y-axis meaning right side simple.
anti clockwise. which means two times also meaning at ( -, -) and (+, +)
Answer:
11/3 ÷ 2/3 = 5 1/2
Step-by-step explanation:
When doing divison of fractions, you do these steps
11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.
11/3 × 3/2. Now all you have to do is multiply
11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2
