Answer:
f(4) = 85 1/3 or 85.333...
Step-by-step explanation:
To find f(4), you must substitute 4 in place of x whenever x appears:
f(x) = [tex]\frac{1}{3}[/tex] * [tex]4^{x}[/tex]
f(4) = [tex]\frac{1}{3}[/tex] * [tex]4^{4}[/tex]
Next, simplify the exponent:
f(4) = [tex]\frac{1}{3}[/tex] * 256
Finally, multiply:
f(4) = 85 1/3 or 85.333...
