Hints

Open one hint at a time and try again before the next.

Hint 1

Zeroes show up where the graph meets the x-axis.

Hint 2

Count how many times the curve meets the x-axis.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. The zeroes of are the -coordinates of the points where the graph meets the -axis.

  2. The curve lies entirely above the -axis and never cuts or touches it. So the number of zeroes is 0. Option (a).
