Question

f(x)=\left\{\begin{array}{ll}x+4&\quad-4\le x < 3\\2x-1&\quad3\le x < 6\end{array}\right.

Answer 1

This is a piecewise defined function. For input values of x between -4 and 3 (exclusive), the function is defined as f(x) = x + 4. For input values of x between 3 and 6 (exclusive), the function is defined as f(x) = 2x - 1.
