The answer to whether an equation can be true or false is; Yes
<h3>Equations</h3>
Yes an equation can be true or false. This is because for example if we have the equation;
3x + 5 < 12
For this equation to hold true, only certain values of x can be possible which we will call as possible solutions. Whereas any values outside of the possible range of x will make the equation to be false.

Number 1s answer would be 2. and number 2s answer would be 2
Discriminant: 24
Solutions: x=−3± the square root of 6
Try this option:
A. f(4)=7 - false; explanation: x=4, it means that x>0 and x²-1=4²-1=15 ⇒ f(4)=15.
B. f(1)=0 - true; explanation: x=1, it means that x>0 and x²-1=1-1=0.
C. f(-1)=2 - true; explanation: x=-1, it means that x<0 and -x+1=1+1=2.
D. f(-2)=0 - false; explanation: x=-2, it means that x<0 and -x+1=2+1=3 ⇒ f(-2)=3.
