Let f(x)=x^3-x-1
alexira [117]
f(x) = x^3 - x - 1

To find the gradient of the tangent, we must first differentiate the function.

f'(x) = \frac{d}{dx}(x^3 - x - 1) = 3x^2 - 1

The gradient at x = 0 is given by evaluating f'(0).

f'(0) = 3(0)^2 - 1 = -1

The derivative of the function at this point is negative, which tells us <em>the function is decreasing at that point</em>.

The tangent to the line is a straight line, so we will have a linear equation of the form y = mx + c. We know the gradient, m, is equal to -1, so

y = -x + c

Now we need to substitute a point on the tangent into this equation to find c. We know a point when x = 0 lies on here. To find the y-coordinate of this point we need to evaluate f(0).

f(0) = (0)^3 - (0) - 1 = -1

So the point (0, -1) lies on the tangent. Substituting into the tangent equation:

y = -x + c \\\\ -1 = -(0) + c \\\\ -1 = c \\\\ \text{Equation of tangent is } \boxed{y = -x - 1}

Please help me answer this question
fredd [130]

Answer:

2t + 16

Step-by-step explanation:

1. 0 seconds and 16 feet.

  • 2(0) + 16
  • 0 + 16
  • 16

2. 1 second and 18 feet.

  • 2(1) + 16
  • 2 + 16
  • 18

3. 2 seconds and 20 feet.

  • 2(2) + 16
  • 4 + 16
  • 20

4. 3 seconds and 22 feet.

  • 2(3) + 16
  • 6 + 16
  • 22

5. 6 seconds and 28 feet.

  • 2(6) + 16
  • 12 + 16
  • 28

Therefore, the answer is 2t + 16.
