given that f x is equal to 12 sin 2x + 5 cos 2x + 20a show that f f x is equal to sign 2x + b into bracket + where A B and C are constants and it been 20 B find the maximum value of F and the corresponding value of x at which it occurs in the interval0 degrees is greater than x is greater than 260 degrees see States the range of ​

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
