Given that the restriction of the cosine function cos to i : = [0, 1] is strictly decreasing and that cos 0 = 1, cos 7 = -1, let ) : = (-1,1), and let arccos: j r be the function inverse to the restriction of cos to i. show that arccos is differentiable on (-1, 1) and d acrccos y = (-1)/(1-2)2 for ye (-1, 1). show that arccos is not differentiable at -1 and 1.

step-by-step explanation:

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
