**Question 16**

Let \( f(x) \) be the function given by:

\[ 
f(x) = 
\begin{cases} 
x + b, & x \leq 1 \\
ax^2, & x > 1 
\end{cases}
\]

Determine all values of \( a \) and \( b \) for which \( f \) is differentiable at \( x = 1 \).

**Options:**

A. \( a = -\frac{1}{2} \) and \( b = -\frac{1}{2} \)

B. \( a = \frac{1}{2} \) and \( b = \frac{3}{2} \)

C. \( a = -\frac{1}{2} \) and \( b \) is any real number

D. \( a = b + 1 \), where \( b \) is any real number
