Apr 15 comment Minimum or maximum area of the triangle formed by a linear function and the axes @dgnamu, you're right, my mistake, I added instead of multiplying… Apr 12 comment Minimum or maximum area of the triangle formed by a linear function and the axes You have $b=2-3a$. When $x=0$, given $y=ax+b$, you must have $y=b$, so $(0,2-3a)$ is on the curve. When $y=0$, it means $ax+b=0$, so $ax+2-3a$ = 0, so $x=3-\dfrac{2}{a}$.

While this is not proof, this is I think the most intuitive answer. Sep 24 comment How is $e^x$ read aloud? In French we would only say “Exponentielle de x” or “e exposant x”.
