-3
-4
Correct answer is A
\(f(x) = mx^{2} - 6x - 3\)
\(f '(x) = \frac{\mathrm d y}{\mathrm d x} = 2mx - 6\)
\(f'(1) = 2m - 6 = 12\)
\(2m = 18 \implies m = 9\)
If \(\log_{9} 3 + 2x = 1\), find x....
The function \(f : F \to R\) = \(f(x) = \begin{cases} 3x + 2 : x > 4 \\ 3x - 2 : x = 4 \\ ...
Solve \(3^{2x} - 3^{x+2} = 3^{x+1} - 27\)...
If the mean of 2, 5, (x + 1), (x + 2), 7 and 9 is 6, find the median. ...
