Find the x-value of all points where the function has relative extrema. Find the value(s) of any relative extrema
1) f ( x ) = x2 +2x - 3
f ( x ) = * 2 + 2 x - 3
f ' ( x ) = 2* +2
f' ( x ) = 0
2 x +2 = 0
2
2 X = - 2
2
X = - /
O
f' ( 0 ) = 2 #
f' ( - 5 ) = - 8 *
At X = - 1 ; A relative minimum exists
J (-1) = (-1) 2 + 2 (- 1)- 3 = -4
the value of x = - 1 is - 4...
