You can use the vertical line test to determine if the graph is a function.
A function must: for every x value have only one y value.
Vertical line test: if you draw a bunch of vertical lines each line only touches the graph once.
So a circle would not be a function, or a horizontally facing parabola, etc... Remember, if you draw a vertical line "|" and it touches the graph more than once at any point then it is not a function.
Now take a look at the graph in the question.
In this graph if we do the vertical line test there are no place where a vertical line touches the graph twice so this graph is indeed a function.
This means your answer is C. Yes
Answer:
The first and third options are correct so choose both
Step-by-step explanation:
Answer:
-3, -4, -5, -6, -7, -8
Step-by-step explanation:
Im not sure if that is what you are looking for or if you want x ≤ -3 and x ≥ -8
Answer:
the answer is false but when it is divided by a negative number then you flip the inequality sign
