Which system of equation can represent the equation?

According to the logarithmic property of the base change, the corrected answer is option one or the first.
 The logarithmic property of base change given that
 logx (b) = logc (b) / logc (x)
 Therefore, the same property applies to this problem and the correct expression for this question is:
 y1 = log (x + 3) / log 4
 y2 = log (2 + x) / log2
