The function g(x) = x is transformed to obtain function h. h(x) = g(x + 7).
Which statement describes how the graph of his different from the graph of g?
OA. The graph of h is the graph of g vertically shifted up 7 units.
ОВ.
Oc.
The graph of his the graph of g vertically shifted down 7 units.
The graph of h is the graph of g horizontally shifted left 7 units.
The graph of h is the graph of g horizontally shifted right 7 units.

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.
