The graph function g(x) is a transformation of the graph of function f(x)=x^2. g(x)= a)2x^2+3 b)-2x^2-3 c)-1/2x2-3 d)1/2x^2-3

A)2x^2+3   is a transformation of f(x)=x^2:  Stretch the graph vertically by a factor of 2 and then shift the entire resulting graph up by 3 units.  The graph will still look like a parabola that opens up.

B)-2x^2-3   is a transformation of f(x)=x^2:  Stretch the graph vertically by a factor of 2, reflect the resulting graph in the x-axis, and then shift the entire resulting graph down by 3 units.  The graph will still look like a parabola that opens down.

Answers to C and D are very similar, except that we compress the graph of x^2 v ertically by a factor of (1/2).

None of these A, B, C, D is wrong.

The answer is -pie over 2
