What restriction should be applied to y = tanx for y = arctanx to be defined? (negative StartFraction pi Over 2 EndFraction, StartFraction pi Over 2 EndFraction)

(negative StartFraction pi Over 2 EndFraction, StartFraction pi Over 2 EndFraction)
Left-bracket negative StartFraction pi Over 2 EndFraction, StartFraction pi Over 2 EndFraction right-bracket

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

not sure but it may be b, as i said i'm not sure.
