Question

What’s all input for f(x)=3

Answer 1

Answer:

all inputs are equal to 3

Step-by-step explanation:

$f(x) = 3 \\ = 3 \times 1\\ = 3 \times {x}^{0} \\ anything \: raised \: to \: 0 \: is \: 1$

$\\ substituting \: any \: value \\ \: of \: x \: in \: f(x) \\ f(3) = 3 \times {3}^{0} \\ = 3 \times 1 \\ = 3$

$\\ similarly \: all \: values \: of \: x \: will \\ give \: 3$
