answer:
it's the second one -7^2-x+2
explanation:
in order to be a quadratic function it has to meet this criteria: ax² + bx + c
- it can't be the first one because there is no bx
- it can't be the third one because there has to be at least an exponent of 2
- it can't be the last one because a CANNOT be 0, hoped this help pls lmk if i'm right lol
