One fact in four languagesSame answer, new clothes

Changes: how the fact is said: value, bracket, solution, graph · Stays the same: the fact $f(3) = 0$

The sketch shows $y = f(x)$ for $f(x) = x^3 - 2x^2 - 5x + 6$. Tick every statement that says the same thing as $f(3) = 0$.
$(x - 3)$ is a factor of $f(x)$$x = 3$ is a solution of $f(x) = 0$the curve crosses the $x$-axis at $x = 3$$(x + 3)$ is a factor of $f(x)$
Read the other two crossings from the sketch and write $f(x)$ as a product of three brackets.

Which of the four could you check by a ten-second substitution, and why do the other three then follow?
