Find the equation of the polynomial function graphed below. The graph of an s-shaped curve with x-intercepts x = -2, 1, 4. f(x) = x3 + 3x2 − 6x − 8 f(x) = x3 − 3x2 − 6x + 8 f(x) = 8x3 + 24x2 − 48x − 64 f(x) = 8x3 − 24x2 − 48x + 64

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.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
