1) function 2) not a function
the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.
the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.
the coordinates for the second one are:
(2,5); (1,1); (1,2); (3,2)
and <u>a function cannot have two same x-coordinates</u>. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function
hope this helps :)
Well, I do not know if I read this correctly. Are these the answers?
-5 ≥ -7
-5 ≤ -7
-5 > -7
-5 < -7
-5 = -7
If so, then -5 > -7 is a true statement because -5 is greater than -7.
Answer:
pls answer my question on my profile
Step-by-step explanation:
Mode: ( The number seem the most )
14. 240
15. 3 and 9
16. 60
Range: ( The biggest and smallest number subtracted )
14. 330-210=120
15. 11-3=8
16. 65-57=8
Answer:
9x² - 7x - 9
Step-by-step explanation:
Two sides
(6x + 7) + 8x = 14x + 7
total perimeter - two sides = Third side
9x² + 7x - 2
- (14x + 7)
––––––––––
9x² - 7x - 9
