The question wants you to find f(5). In other words, find the value of this equation if “x” were to equal 5. Replace the “x” in this equation with a 5:
f(5) = (1/4) × 2^5
Simplify, starting with the exponent:
f(5) = (1/4) × 32
Multiply:
f(5) = (32/4)
Fully simplify the right side of the equation:
f(5) = 8
The answer is 8.
I hope this helps!
