Answer:
See below
Explanation:
The parabola defined by 2x^2 - 7x - 4 is being restricted by the condition that all solutions must be less than zero. If we write this as an equation:
y = 2x^2 - 7x - 4,
it tells us that y will always be less than zero. or 2x^2 - 7x - 4 < 0
This can be graphed (see attachment). We find a very lonely part of a parabola. The only solutions are those on the line that is visible, despite the lofty expectations of the x^2 member of this function. The fact that this is written as <0 and not as ≤0, means that even the two points where the curve touches the x axis are even excluded. Insult to injury (the metric term).
