Welcome to ATP mip and I agree with Evan your plant looks like one of the upright elephant ears Alocasias. First of all the yellowing leaves are a sign of not enough light or too much water or both. That pot doesn't look like it has any drain holes. And as Evan stated Alocasias need well draining soil. Try letting soil dry out abit between watering and give it morre sun. Im no expert by far but hate to see anyone lose a plant. Keep us updated on how it's going.
