$f(x) = 4x$ by differentiating from first principles. Answer: [blank_start]4[blank_end]

Answer

Question 2

Question

Which of the following is the derivative of the following equation:

$y= 6x^2 + ^3 \sqrt{4x^2}$

Answer

$\frac{dy}{dx}=12x + \frac{8}{3x^3}$
$\frac{dy}{dx}=12x + \frac{8x^3}{3}$
$\frac{dy}{dx}=12x + \frac{8}{3}$

Question 3

Question

$x$ represents displacement and

$t$ represents time, then which of the following represents acceleration?

Answer

$x'(t)$
$\frac{dx}{dt}$
$x''$

Question 4

Question

Answer

True
False

Question 5

Question

The derivative of the function

$f(x) = 4x^2 + 5x^3 + 16$ is given by...

Answer

$f'(x) = 8x + 15x^2$
$f'(x) = 12x^3 + 15x^4$
$f'(x) = 8x + 15x^2 +16$
