(1) Equation $\displaystyle f(x) = g(x)$ has at most one real (R) solution.

$\displaystyle \exists ! x \in \mathbb{R} . f(x) = g(x)$

(2) Equation $\displaystyle f(x) = g(x)$ has more than one real (R) solution.

$\displaystyle \exists x \in \mathbb{R} . f(x) = g(x)$

(3) Equation $\displaystyle f(x) = g(x)$ has 2 real (R) solutions.

no clue for (3)

I know I did (1) wrong.. at most 1 means 1 or 0.. i wrote for 1.

(2) doesn't tell how mayn solutions there are; there could only be 1.
