Domain : -5,-3,0,1,2
range : 1,2,3,1,0
It is not a function because for two values of x( -5 and 1) we have one value of y which contradicts the definition of function

Answer:
7x+1
Step-by-step explanation:
When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.
First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.
Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.
Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.
Your answer is 7x+1.
Answer:
b
Step-by-step explanation:
2 times x is 6 so the first number has to be a 3
Answer:
y=2/3x-2
Step-by-step explanation:
A linear equation is in the form of y=mx+b
You need to find the slope and y-intercept.
The slope is 2/3 Up 2, over 3 to the right.
The y-intercept is (0,-2)
So the equation would be, y=2/3x-2
Hope this helps :)
