    B and D are exponential graphs. The equation for D would be something like y = a^x (where a is a positive constant) and the equation for B would be y = a^-x. If you think about it, you should be able to work out why those graphs have this shape. EDIT: I thought you were asking about those two graphs because you had circled them. If you are asking for help with the questions on the sheet then i), as you correctly identified, is E. For ii) we have the equation of a line of gradient and y-intercept at the origin. Which graph does that look like?

    They're reciprocal graphs that's why

    No, they're not reciprocals. They're exponentials. If they were reciprocals, there would be a vertical asymptote as well as a horizontal one

    What specifically are you asking us to help you with? All of the graphs or just B and D?
