Answer :
The correct option is c. f(3) for [tex]f(x) = 5^x - 12[/tex] is 113.
To find [tex]\( f(3) \)[/tex] for [tex]\( f(x)[/tex] = [tex]5^x - 12 \)[/tex]:
[tex]\[f(3) = 5^3 - 12\][/tex]
Calculate 5³:
[tex]\[5^3 = 125\][/tex]
Subtract 12 from 125:
[tex]\[125 - 12 = 113\][/tex]
[tex]\( f(3) = 113 \)[/tex]
The complete question is
