Guys help me please please please

Answer:
[tex]\left[\begin{array}{ccc}1&\frac{3}{4}\\2&\frac{9}{16}\\3&\frac{27}{48}\\4&\frac{81}{144}\end{array}\right][/tex]
Step-by-step explanation:
[tex]f(s) = \frac{3}{4} * f(s - 1)[/tex]
It is basically substituting the numbers in the function.
For 1, it will be
[tex]f(1) = \frac{3}{4} * f(1 - 1)[/tex]
[tex]f(1) = \frac{3}{4} * f(0)[/tex]
[tex]f(1) = \frac{3}{4} * 1[/tex]
[tex]f(1) = \frac{3}{4}[/tex]
Same for the rest.
