Solution

(a) The derivative of the function f(x) = x^2 + 3.5x - 6 is given by f'(x) = 2x + 3.5. This is obtained by applying the power rule of differentiation.

(b) To find the relative extreme points, we need to set the derivative equal to zero and solve for x. This is because at the extreme points (maximum or minimum), the slope of the tangent (which is the derivative) is zero.

So, we set f'(x) = 0:

2x + 3.5 = 0

Solving for x gives x = -3.5/2 = -1.75.

To determine whether this point is a maximum or a minimum, we can use the second derivative test. The second derivative of the function is f''(x) = 2 (a constant). Since this is positive, our point is a relative minimum.

To find the y-coordinate of this point, we substitute x = -1.75 into the original function:

f(-1.75) = (-1.75)^2 + 3.5*(-1.75) - 6 = -6.5625.

So, the relative minimum point is (-1.75, -6.5625).

The function does not have a relative maximum point, so we can say it does not exist (DNE).
