Take the deritive
y'=-3sinx
find whre it equals 0
it equals 0 at -pi, 0, pi, etc
find whre it changes from negative to positive
at -0.5pi, the derivitive is positive
at 0.5pi, the deritivie is negative
changes from positive to negative at x=0
that means that the max values are at pi and -pi in 2pi intervals
-pi, pi, 3pi, 5pi,etc
the min y value is -3
so the minimum(s) are/is at (2aπ,-3) where 'a' is an integer
Answer:
y=1 (sorry i dont know what justify means lol, i forgot) i know how to solve the answer lol.
Step-by-step explanation:
10y-15-4y=8-2y-15
10y-4y+2y=8-15+15
8y=8
y=1
Y=14.5
X= 5
Hope this helps :)
