Use interval notation to write the intervals over which \( f \) is a) increaving, b) decreasing. and c) constant. a. \( (-\infty, 2) \) b. \( (2, \infty) \) \( w_{n} x=2 \) a) \( (-\infty,-1) \) b. \( (-1, \infty 6) \) c. never constani a. \( (-\infty,-2) \) b. \( (-2,-\infty) \) c. never constant a) \( (-\infty, 2) \) b. \( (2, \infty) \) 6. never constant Identify the location and value of any relative maxima or minima of the functios At \( x=-3 \), the finction has a relative minimum of \( -5 \). At \( x=0 \), the function has a relative maximum of 0 . At \( x=3 \), the function has a relative minimum of \( -5 \). At \( x=-3 \), the function has a relative mainiram of 0 . \( \mathrm{At} x=0 \), the function has a relative maximum of 0 . At \( x=3 \), the function has a relative minimem of 0 . At \( x=-4.2 \), the function has a relative minimam of 0 . At \( x=0 \), the function has a relative maximum of 0 . At \( x=4.2 \) the function has a relative minimum of 0 . At \( x=-3 \), the function has a relative minimam of of. At \( x=3 \), the function has a relative minimum of \( -5 \). to take the quiz alone, without the assistance of others or the interriet 84 calculator.
