No, because when graphed they do not meet at 90 degree angles
Answer:
it's part of the real number system
it's a rational number
it's an integer
Step-by-step explanation:
When x = 2 then f(x) = 2^2 +2(2) -1 = 4 + 4 - 1 = 7
when x = 3 then f(x) = 3^2 +2(3) -1 = 9 + 6 - 1 = 14
when x = -3 then f(x) = (-3)^2 +2(-3) -1 = 9 - 6 - 1 = 2
(-3,2) (2, 7) and (3,14)
answer
Pairs
2 ------> -3
14 ------> 3
7 ------> 2
It was chord less sorry if wrong
Ummm I’m not sure but maybe try 8 x 60, and then divide your answer with 130
