based on the 60-30 special triangle, you can find the lengths of all the sides with only one side length. The hypotenuse is double the length of the short leg and the longer leg is found by multiplying the shorter leg by √3.
The answer is obvious that is option B, however for educational purposes we will graph the different cases
using a graph tool
see the attached figure
case A-------> is a parabola is not a straight line
case B-------> is a straight line
case C-------> there are two straight line
case D-------> is a circle is not a straight line
hence
the answer is the optionB.f(x) = x + 1
