T(z)= sin^2(z/4), {-3 ≤ z ≤ 8} identify the intervals where:
a) T(z) is increasing
b)T(z) is decreasing
C)T(z) is concave up
d)T(z) is concave down
Then identify the
e) absolute minimum and where it is
f) A relative maximum ( not absolute maximum and where it is

please help

answer: check all that apply, where the options?

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
