Pls help me! Pls show work so I know how to do it if you can’t then it’s fine! Thank you!

[tex]\sf f(x) = 5(-2)^{\small{\dfrac{x}{6}}}[/tex]
For evaluating the given function at f(24) just substitute x = 24
[tex]\sf f(24) = 5\times(-2)^{\small{\dfrac{24}{6}}}[/tex]
[tex]\longrightarrow \sf f(24) = 5\times (-2)^4[/tex]
[tex]\longrightarrow \sf f(24) = 5 \times 16 [/tex]
[tex]\longrightarrow \sf f(24) = 80 [/tex]
