For part A, you have the y intercept. Substitute x=1 to the equation to get y value. You have 2 points for 1 straight line, hence draw a line through both points.
For part B, you are recommended to remember what the graph looks like, and also what other graphs of such equations look like. But for this case, increasing x value will decrease in y value, and the decrease is exponential. Note since it is x^2, negative values will also give the same values, therefore the y axis acts as a mirror.
Similarly for part C, you are recommended to remember this, but you can try sketching it by substituting different increasing values of x. However in this case, the y value increases exponentially.
Try it out in your own and see if it matches. Hope it helps!
