Here are two graphs representing the functions of 𝑓 and 𝑔. Identify at least two

values of 𝑥 at which the inequality 𝑔(𝑥) > 𝑓(𝑥) is true.

• 𝑓(𝑥) = 𝑔(𝑥) for exactly two values of x

• 𝑓(𝑥) = 𝑔(𝑥) for exactly 1 value of x

• 𝑓(𝑥) < 𝑔(𝑥) for all values of x

• 𝑓(𝑥) > 𝑔(𝑥) for all values of x

• 𝑓(𝑥) is the inverse of 𝑔(𝑥)
