option C

Step-by-step explanation:
$\begin{gathered} \text{Given:} \\ f(x)=x^2 \\ We\text{ want to find the graph of f(2x)} \\ \\ \text{For positive co}efficient,\text{ parabola opens up} \\ \text{For negative coefficient, parabola opens down} \end{gathered}$

Since the coefficient of x² is positive, then the graph will open up

We are left with option C and D

Plotting f(x) = x²

plotting g(x) = f(2x)

We see the grapg of f(2x²) is more narrow than graph of f(x) = x²

Hence, the graph of g(x) = f(2x) is option C
