Answer:
A.
Step-by-step explanation:
A quadratic inequality looks like a quadratic equation, but with signs
<, >, ≤, or ≥
instead of sign =
You are given one equation (the first one, because the sign is =) and two inequalities (the last two beacause the signs are < and > respectively).
Thus, correct option is A,
[tex]y=7x^2+5x-7[/tex]
is not a quadratic inequality (it is a quadratic equation)
