Which graph shows the solution to the inequality -0.5x ?= 7.5?
A number line going from negative 18 to negative 8. A closed circle is at negative 15. Everything to the right of the circle is shaded.
A number line going from negative 18 to negative 8. A closed circle is at negative 15. Everything to the left of the circle is shaded.
A number line going from negative 5 to negative 2.5. A closed circle is at negative 4. Everything to the right of the circle is shaded.
A number line going from negative 5 to negative 2.5. A closed circle is at negative 4. Everything to the left of the circle is shaded.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
