Answer:
[tex]\frac{1}{243}[/tex]
Step-by-step explanation:
using the rule of exponents
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]
f(- 5) = [tex]3^{-5}[/tex] = [tex]\frac{1}{3^{5} }[/tex] = [tex]\frac{1}{243}[/tex]
Answer:
f(-5) = 1/ 243
Step-by-step explanation:
f(x) = 3^x
Let x=-5
f(-5) = 3^-5
Since the exponent is negative, it will move to the denominator
f(-5) = 1/3^5
f(-5) = 1/ 243
