Answer:
[tex]\huge\boxed{\sf f(-2) = 3.25}[/tex]
Step-by-step explanation:
Given function is:
[tex]f(x) =2^x+3[/tex]
Put x = -2
[tex]\displaystyle f(-2) = 2^{-2}+3\\\\f(-2) = \frac{1}{2^2} + 3\\\\f(-2) = \frac{1}{4} + 3\\\\f(-2) = 0.25+3\\\\f(-2) = 3.25\\\\\rule[225]{225}{2}[/tex]
Hope this helped!
