The graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of
f(x) = 8x^2-6. Write a rule for g. Then identify the vertex.
f(x) = a (x -h)2 + k horizontal stretch by a factor of 2 -> 1/2 x 2 units up -> k = 2 reflection in y axis -> x value is negative g(x) = 8*(1/2 x)2 - 6 + 2 g(x) = 2 x2 -4
