Correct answer is A
\(f(x) = p + qx\)
\(f(1) = p + q(1) \implies p + q = 7 .... (1)\)
\(f(5) = p + 5q = 19 .....(2)\)
Solving for p and q using simultaneous equation, p = 4, q = 3
\(f(3) = 4 + 3(3) = 13\)
Express \(\frac{8 - 3\sqrt{6}}{2\sqrt{3} + 3\sqrt{2}}\) in the form \(p\sqrt{3} + q\sqrt{2}\)...
