F (x) = 3•2^x+10+9 what's the range

The range is from 19 up to infinity. As x gets really negative, like - 10,000 and - 100,000, 2^x becomes closer and closer to 0; when it becomes essentially negative infinity, the value of 2^x becomes 0. As x gets really positive, the value of 2^x becomes extremely large.

The range of this function is from 19 to infinity.
