Answer:
all inputs are equal to 3
Step-by-step explanation:
[tex]f(x) = 3 \\ = 3 \times 1\\ = 3 \times {x}^{0} \\ anything \: raised \: to \: 0 \: is \: 1 \\ [/tex]
[tex] \\ substituting \: any \: value \\ \: of \: x \: in \: f(x) \\ f(3) = 3 \times {3}^{0} \\ = 3 \times 1 \\ = 3 \\ [/tex]
[tex]\\ similarly \: all \: values \: of \: x \: will \\ give \: 3[/tex]
