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

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

c

-by-step explanation:

it would be c
