Answer:
8
Step-by-step explanation:
I know it is b I had this I had this question before
Let's break down each part of this question into math symbols. It's cooler to think of it like one of those codes they make you crack in primary school.
Three: 3
Times: * (multiplication)
A number: x
Less two: –2
Is greater than: >
Two: 2
No more than: <
Seven: 7
So 3*x–2>2
But also
3*x–2<7
Solving the first equation, add two to both sides:
3x>4
Divide both sides by 3:
X>4/3 (4/3 is about 1.33)
Solving the second equation, add two to both sides:
3x<9
Divide both sides by 3:
x<3
So the number we want is bigger than 1.33 but less than 3 which makes the answer:
2
Hope that helped! :)
Answer:
1. Number 1 and 2 and 4 is a function, 2. number 1 is a function
Step-by-step explanation:
1)To know if it's a function or not run vertical lines through multiple places of the graph. If it is a function every single time you do the vertical line test it should only go over the line once. If you do the vertical line test on 3 you will see that it went over the line on the graph, so we know not a function. Graphs 1, 2, and 4m however, are different, when you do the vertical line test on those graphs it only goes over them once.
2) Choice (1) is a function because when drawing vertical lines through the graph it only goes over one.
Choice (2) is not a function because when drawing vertical lines through the graph it covers two points on the graph.
Choice (3) is not a function because when drawing vertical lines through the graph it goes over multiple points.
Choice (4) is not a function because when a vertical line is drawn, it goes over more than one point on the graph.
The vertical test is a way to determine if it is a function.
When looking at a table functions are one-to-one and many-to-one
Non-functions are one-to-many and many-to-many
Hoped this helped you : )
