PLS HELP AND EXPLAIN HOW TO DO THIS, ILL GIVE BRAINLIEST

Answer:
C. 8
Step-by-step explanation:
f(5) =1/4(2)^5
because x=5
f(5)=1/4(32)
because 2^5 is 2*2*2*2*2=32
f(5)=8
because 1/4*32 or 32/4 is 8
Hope this helped :) I haven't even learned f(x) in school yet haha. I'm in 8th grade, but I took extracurriculars for math and I'm on the math team. Ergo, I know it's right!
