Answer: 1 or 2
Step-by-step explanation: Hope I helped please give a heart ;)
Hello,
The graph of y = x² + 1 most certainly is a function.
It is a function because for every value of x, there is only one value of y.
The domain of y = x² + 1 is the set of all real numbers and the range is y ≥ 1.
<span>hypothesis :-
if x=30, then 3/4x+5≠20
let Q:- x=30 P:- 3/4x+5≠20
we need to prove if Q then P (Q →P)
proof :-
lets assume 34x+5=20 is true
now x=30
so
3/4(30)+5=27.5 ≠20
which is a contradiction
proved ^</span>
