For what value or values of the constant kk, if any, is the function g(x)g(x) defined as g(x)={sinx, if x<0kx2, if x≥0g(x)=\(\begin{cases}\]\sin\) x,\(\text{ if }\)x<0\\ kx^2,\(\text{ if }\)x\(\ge\)0\(\end{cases}\), continuous at x=0x = 0 and differentiable at x=0x = 0?

For what value or values of the constant $k$ , if any, is the function $g (x)$ defined as $g of x equals 2 cases Case 1: sine x comma if x is less than 0 Case 2: k x squared comma if x is greater than or equal to 0$ , continuous at $x equals 0$ and differentiable at $x equals 0$ ?
