Answer:
It is skinner and higher up on the graph by 4 units.
Step-by-step explanation:
The coefficient of 2 on the x² of the equation f(x)=2x²+4 dilates it vertically by 2, making it much skinnier than than f(x)=x².
Additionally, the constant 4 added on the end translates the whole parabola up by 4.
