To compute dy for the given function, we start by finding the derivative of the function with respect to x. The function is:
y = x² + 6x
We differentiate y:
dy/dx = 2x + 6
Next, we substitute the value of x = 5 into the derivative:
dy/dx at x = 5:
dy/dx = 2(5) + 6 = 10 + 6 = 16
Now that we have dy/dx, we can compute dy using the formula:
dy = (dy/dx) * dx
Substituting dy/dx and dx:
dy = 16 * 0.5 = 8
In summary:
- dy/dx = 16
- dy = 8
