Question

If you horizontally compress exponential function f(x)=2^x by a factor by a of 5, which of these is the equation of the new function?

Answer 1

the anwser is -2x my dude

Answer 2

Answer: A.
`f(5x)=2^(5x)`

Explanation:

When we compress a function
`y= f(x)` by a scale factor of 'k', where k >1, then the function after compression will become :

`y= f(kx)`, where k>1

Given: Exponential function:
`f(x)=2^x`

The scale factor of the compression (k): 5

Then after horizontally compression , the exponential function will become :

`f(5x)=2^((5x))`
