Find the first 3 iterations using f(x)=3x if you have an initial value of 1 show work
enot [183]

Answer:

You need to replace the x with the value that you want to evaluate. If the initial value is 1, you have to replace the x with1, then with 2, an finally with 3.

<em>Iteration 1.</em>

f(x=1)=3*(1)

f(x=1)=3

<em>Iteration 2.</em>

f(x=2)=3*(2)

f(x=2)=6

<em>Iteration 3.</em>

f(x=3)=3*(3)

f(x=3)=9
