1. Simplify. Be sure to state the restrictions on the variables.

2. Simplify Completely. State the domain.

3. Use the relation {(–4, 3), (–1, 0), (0, –2), (2, 1), (4, 3)} to answer the following questions

a. Graph the relation.

b. Is the relation a function? How do you know?

4. Complete. Factor: 2x^2 – 5x – 3.

1)please send me the equation of number 1.

2)send the equation of number one

3) a. plotting the graph it is a U-shaped curve with a minima at (0,-2)

b. the graph is a function, because when we assume that it is a straight line then picking two points randomly, the gradients are not the same.

4). 2x^2-5x-3 can be written as 2x^2-6x+x-3

factoring the equation, 2x(x-3)+1(x-3)

2x^2-6x+x-3=(2x+1)(x-3) domains are all real numbers

This is the file my math teacher gave me and my class mates.
