B Correct answer
Explanation

The equation of the tangent line to a curve $y = f(x)$ at the point $(x_1, y_1)$ is given by the formula $y - y_1 = f'(x_1)(x - x_1)$. Finding the derivative of the given function, we get $f'(x) = 2x - 2$. Substituting the point $(1, 0)$, we get $f'(1) = 2(1) - 2 = 0$. Therefore, the equation of the tangent line is $y - 0 = 0(x - 1) = -x + 1$. Simplifying, we get $y = -x + 2$.

A Correct answer
Explanation

To find the equation of the tangent line, we need to find the slope of the curve at the point ((1, 0)). The slope is given by the derivative of the function, which is (f'(x) = 3x^2 - 4x + 3). Substituting (x = 1), we get (f'(1) = 3(1)^2 - 4(1) + 3 = 2). Therefore, the equation of the tangent line is (y - 0 = 2(x - 1)), which simplifies to (y = x - 1).

Multiple choice

What is the equation of the tangent line to the curve (y = \frac{x^3}{3} - 2x^2 + 4x - 5) at the point ((2, 1))?

  1. \(y = 5x - 9\)
  2. \(y = 5x + 9\)
  3. \(y = 3x - 1\)
  4. \(y = 3x + 1\)

C Correct answer
Explanation

To find the equation of the tangent line, we need to find the slope of the curve at the point ((2, 1)). The slope is given by the derivative of the function, which is (f'(x) = x^2 - 4x + 4). Substituting (x = 2), we get (f'(2) = 2^2 - 4(2) + 4 = 0). Therefore, the equation of the tangent line is (y - 1 = 0(x - 2)), which simplifies to (y = 3x - 1).

Multiple choice

Which of the following integrals represents the length of the curve (y = x^3 - 2x^2 + 3x - 4) from (x = 0) to (x = 2)?

  1. \(\int_0^2 \sqrt{1 + (3x^2 - 4x + 3)^2} dx\)
  2. \(\int_0^2 \sqrt{1 + (3x^2 - 4x + 3)^2} dx\)
  3. \(\int_0^2 \sqrt{1 + (3x^2 - 4x + 3)} dx\)
  4. \(\int_0^2 \sqrt{1 + (3x^2 - 4x + 3)^2} dx\)

A,B,D Correct answer
Explanation

To find the length of the curve (y = x^3 - 2x^2 + 3x - 4) from (x = 0) to (x = 2), we need to use the formula (L = \int_a^b \sqrt{1 + (\frac{dy}{dx})^2} dx), where (\frac{dy}{dx}) is the derivative of the function that defines the curve and ([a, b]) is the interval of integration. In this case, (\frac{dy}{dx} = 3x^2 - 4x + 3) and ([a, b] = [0, 2]).
