Can someone help with these

Answer:
[tex]y=4^x\Rightarrow\begin{array}{c|cc}x&y\\in put&o utput\\1&4\\2&16\\3&64\\4&256\\5&1024\\\end{array}\\\\y=-3^x\Rightarrow\begin{array}{c|cc}x&y\\in put&o utput\\1&-3\\2&-9\\3&-27\\4&-81\\5&-243\end{array}\\\\[/tex]
Step-by-step explanation:
Put the values of x (input) to the formulas of the functions
[tex]y=4^x\\\\x=1\to y=4^1=4\\\\x=2\to y=4^2=16\\\\x=3\to y=4^3=64\\\\x=4\to y=4^4=256\\\\x=5\to y=4^5=1024\\===================\\\\y=-3^x\\\\x=1\to y=-3^1=-3\\\\x=2\to y=-3^2=-9\\\\x=3\to y=-3^3=-27\\\\x=4\to y=-3^4=-81\\\\x=5\to y=-3^5=-243[/tex]
