Please help me, I can't understand
2 answers:
check out the document I have uploaded, and the things I have done in blue; that's how you should show the inequality x>5/2
I have colored the right side because x is greater than 5/2, so instead of coloring the left side because if I color the left side it means that x is less but mow you get the inequality as x greater so you should color the side which increases
the left side means that it decreases
(I wanted to help you with the drawing since you already go help with solving and finding the inequality) Have a great day and I hope this helps

Answer:
Both equation represent functions
Step-by-step explanation:
The function is the relation that for each input, there is only one output.
A. Consider the equation
This equation represents the function, because for each input value x, there is exactly one output value y.
To check whether the equation represents a function, you can use vertical line test. If all vertical lines intersect the graph of the function in one point, then the equation represents the function.
When you intersect the graph of the function with vertical lines, there will be only one point of intersection (see blue graph in attached diagram). So this equation represents the function.
B. Consider the equation
This equation represents the function, because for each input value x, there is exactly one output value y.
When you intersect the graph of the function with vertical lines, there will be only one point of intersection (see green graph in attached diagram). So this equation represents the function.
