Answer:
Step-by-step explanation:
we want y by itself...sooo
y - 19 = - 
(x - (-5))
y - 19 = - (x+5)
y - 19 = - x - 
y = - x - 3 +19
y = - x + 16
Answer:
x = -3
Step-by-step explanation:
The vertex lies on the axis of symmetry, whose x-coordinate is halfway between -9 and 3: x = -3

Answer:
y=tan x and y=cotx
Step-by-step explanation:
We are given functions of all trignometric ratios and asked to find out which has range of all real numbers. Let us discuss one by one
1. y =sinx: False because -1≤sinx≤1 always
2. y=cosx:False because -1≤cosx≤1 always
3. y = tanx: True because tanx can take any value
4. y=cot x: True because cots x can take any value
5. y = csc x: False because this range does not lie between -1 and 1
6. y=sec xFalse because this range does not lie between -1 and 1
