Write the slope and y-intercept of this linear equation: 3y + 6 = –2x
netineya [11]

Answer:

slope = -2/3

y-intercept = -2

Step-by-step explanation:

3y + 6 = -2x

Conver to slope intercept form

3y = -2x - 6

y = -2/3x - 2

Follow the form y = mx + b, so m is the slope and b is the y-intercept

What is the domain of y = cos ^-1x?
Bas_tet [7]

Answer:

Step-by-step explanation:

Correct option is

D

[1,(1+π)  

2

]

f(x)=(1+sec  

−1

(x))(1+cos  

−1

(x))

Here the limiting component is cos  

−1

(x), since the domain of cos  

−1

(x) is [−1,1].

Therefore,

f(1)=(1+0)(1+0)

=1

f(−1)=(1+π)(1+π)

=(1+π)  

2

 

Hence range of f(x)=[1,(1+π)  

2

]
