Question

The function g(x) =2^x.The function f(x) =2^x+k and k<0

Which of the following statements is true?

Answer 1

Answer:  D. f(x) is k units below g(x)

Step-by-step explanation:

We're comparing for example g(x)=2^x and f(x)=2^x -1.  They're identical except the latter is one unit below the former.  

Answer 2

Answer:

Has to be C, the other dude got the same answer I originally got. If the graph is plugged in with a number less than 0, the graph will appear below the original, if plugged with a number above 0 then it will be higher

Step-by-step explanation:

Graphing with Demos, depicts the exponential function f(x) to be above the original function, a way to test this is by plugging in any number less than 0
