What is the range of g(x)=3(2)^x-1?

A. all real numbers
B. all real numbers greater than or equal to 5
C. all real numbers greater than -1
D. all real numbers greater than or equal to -1

Respuesta :

This one is C since the graph of 3(2^x) approaches 0 and does not touch zero so if we subtract 1 then the limit would be -1
