Answer:
f(-2) = 0.4
Step-by-step explanation:
The given function is f(x) = 5ˣ
and we have to find the value of f (-2)
We will substitute x = -2 in the given function.
f(x) = 5ˣ
f(-2) = (5)⁻²
Since x⁻¹ = [tex]\frac{1}{x}[/tex]
so f(-2) = [tex]\frac{1}{5^2}[/tex]
[tex]\frac{1}{25}[/tex]
= 0.04
Therefore, f(-2) = 0.4 is the answer.
