Please help with this question for calculus involving interval notation and x values with min and maximum values.

(1 point) Suppose that f(x)=(x+2)(x−2)2.

(A) Find all critical values of f. If there are no critical values, enter -1000. If there are more than one, enter them separated by commas.
Critical value(s) =

 

(B) Use the second derivative test to find the x-coordinates of all local maxima of f. If there are no local maxima, enter -1000. If there are more than one, enter them separated by commas.

Local maxima at x =

 

(C) Use the second derivative test to find the x-coordinates of all local minima of f. If there are no local minima, enter -1000. If there are more than one, enter them separated by commas.

Local minima at x =

f(x) = 7/x2 - 16 List all critical numbers of f . If there are no critical numbers, enter 'NONE'. Critical numbers = Use interval notation to indicate where f (x ) is increasing. Note: Use INF for infinitive, '-INF for - infinitive. and use 'U' for the union symbol. Increasing: Use interval notation to indicate where f ( x ) is decreasing. Decreasing: List the x-coordinates of all local maxima of f . If there are no local maxima, enter 'NONE'. x values of local maxima = 0 List the x-coordinates of all local minima of f . If there are no local minima, enter 'NONE'. x values of local minima = Use interval notation to indicate where f ( x ) is concave up. Concave up: Use interval notation to indicate where f ( x ) is concave down. Concave down: List the x values all inflection points of f . If there are no inflection points, enter 'NONE'. Inflection points = List all horizontal asymptotes of f . If there are no horizontal asymptotes, enter 'NONE'. Horizontal asymptotes y = List all vertical asymptotes of f . If there are no vertical asymptotes, enter 'NONE'. Vertical asymptotes x =

)e* (1 point) Suppose that f(z) = (7-3a Note: Several parts of this problem require answers entered in interal.notation. Note, with interval notation, you can enter the empty set as I. A)List all the critical values of f(x). Note: If there are no critical values, enter NONE (B) Use interval notation to indicate where f(reasing. Increasing (C) Use interval notation to indicate where f() is decreasing Decreasing: (D) List the z values of all local maxima of f(). If there are no local maxima, enter NONE r values of local maximums (E) List the z values of all local minima of f(z)·lf there are no local minima, enter NONE. r values of local minimums (F) Use interval notation to indicate where f(x is concave up. Concave up: (G) Use interval notation to indicate where f(z) is concave down. Concave down: (H) List the r values of all the inflection points of f. If there are no inflection points, enter NONE. z values of inflection points = (I) Use all of the preceding information to sketch a graph of f Include all vertical and/or horizontal asymptotes.
