Task 253
Task 253: test task in emrekuruu/math-openenv, an RL environment on the Hugging Face Hub. Consider the two functions $f(x) = x^2 + 2bx + 1$ and $g(x) = 2a(x + b),$ where the variables $x$ and the constants $a$ and $b$ are real numbers. Each such pair of constants $a$ and $b$ may be considered as a…
The task
Consider the two functions $f(x) = x^2 + 2bx + 1$ and $g(x) = 2a(x + b),$ where the variables $x$ and the constants $a$ and $b$ are real numbers. Each such pair of constants $a$ and $b$ may be considered as a point $(a,b)$ in an $ab$-plane. Let $S$ be the set of points $(a,b)$ for which the graphs of $y = f(x)$ and $y = g(x)$ do not intersect (in the $xy$-plane). Find the area of $S.$
