Find an expression for the gradient of the function \[f(x) = 4x\] by differentiating from first principles. Answer:
Which of the following is the derivative of the following equation: \(y= 6x^2 + ^3 \sqrt{4x^2}\)
\[\frac{dy}{dx}=12x + \frac{8}{3x^3}\]
\[\frac{dy}{dx}=12x + \frac{8x^3}{3}\]
\[\frac{dy}{dx}=12x + \frac{8}{3}\]
If \(x\) represents displacement and \(t\) represents time, then which of the following represents acceleration?
\( x'(t) \)
\(\frac{dx}{dt}\)
\(x''\)
The second order derivative is zero at a local maximum.
The derivative of the function \[f(x) = 4x^2 + 5x^3 + 16\] is given by...
\(f'(x) = 8x + 15x^2\)
\(f'(x) = 12x^3 + 15x^4\)
\(f'(x) = 8x + 15x^2 +16\)
The graph of the derivative of this curve would have which shape?
Differentiate the following function:\[f(x) = \frac{3x^2+18x+8}{3x+2}\]. \(f'(x)\) =
What is the gradient of the normal to the curve \[y= x^4 + 3x^2\] at the point \((1, 4)\)? The gradient is .
