Answer:
YES it undercuts Federalism
Step-by-step explanation:
Implied powers are powers that congress can exercise in order to fulfill an obligation or power that is granted to the congress explicitly by the constitution.
The implied power itself is not explicitly stated in the constitution but it right to execute does powers because they are born out of necessity. Implied powers undercuts Federalism because in federalism the regions/states share the Governing power as stated in the constitution. since the implied powers are not explicitly stated the state/regions can't share those powers with the Federal Government.
