1. ## Exponential Function

2 -x+5= 16 small exponent x

I don't know how to make the -x+5 smaller but this equation is above the 2

2. If x=1, is the equation true?
Why do you think that it works that way?

3. i c . it would work because -1+5 = 4 2 to the fourth = 16

4. in this equation do i replace x with 1?

3 x to the second power minus 4 = 27 exponent x
the x square - 4 is above the 3

5. You see how easy it is?
You just had to notice that 16 is a power of 2.
