Use a graphing utility to approximate (to two decimal places) any relative
minima or maxima of the function. (if an answer does not exist, enter dne.)
f(x) = x(x + 7)
relative minimum
(x, y) =
relative maximum
(x, y) =

Relative minima at , and relative maxima DNE.

Step-by-step explanation:

The given function is f(x) = x (x + 7) ...... (1)

We have to calculate the relative maxima and relative minima at point (x, y).

Rearranging the function given above we get.

⇒

Now, this is an equation of parabola having vertex at and the axis is parallel to positive Y-axis.

Therefore, the function(1) has a relative minima at , and the relative maxima DNE. (Answer)
