Question

Evaluate the function rule for the given rule. f(x)=3^x for x=-5 PLEASE HELP

Answer 1

I believe you would just substitute -5 for x.
So
f(x)=3^-5
and you would get f(x)=0.0041
which you can round to f(x)=0.004

Answer 2

f(x) = 3^-5 would equal 1/243x if you’re solving for X, however it would equal 1/243f if you’re solving for F!

Hope this helps :)
