What are the common mistakes in Key points on exponential and trigonometric graphs?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Assumed exponential graph crosses x axis

  Assumed the graph must cross the x-axis somewhere, not recognising that $8^x > 0$ for every value of $x$, so the graph gets arbitrarily close to the x-axis but never touches it.

• Substitutes the wrong exponent value into a formula, using a nearby fraction instead of the one actually given

  Applies the wrong exponent when checking the second point, e.g. computing k^(1/3) instead of k^(1/2).

• Confused cosine x intercepts with sine
