Description
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.
Explanation & Answer
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
