Question

How do you solve `y <=-2x^2 + 5x + 6`?

Answer 1

The set of points {(x, y)) for the given inequality is given by the parabola #y=-2x^2+5x+6 and the region with.n the parabola. Draw the parabola and shade this set of points..

Explanation:

The given inequality could be rearranged to the form

`y-37/2<=-2(x-5/2)^2`/

For the equality sign, this represents the parabola, with vertex V(5/2,

37/2), axis parallel to y-axis, downwards.The focus is S(5/2, 18).

For any point inside this parabola, y < y in (x, y) right above on the

parabola.
