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
