  b.  g(x) = 2x²

Step-by-step explanation:

The vertices of the two curves are in the same place, so no translation has taken place. This eliminates choices 'a' and 'd'.

A point on the curve g(x) is given. You can test to see which of choices 'b' and 'c' it satisfies.

  B: g(2) = 2(2²) = 8 . . . . matches point (2, 8)

  C: g(2) = (1/2·2)² = 1² = 1 . . . . does not match point (2, 8)

The function g(x) is ...

  g(x) = 2x²

where are the options?
