Domain: all reals
If you need it in interval notation, its (-[infinity symbol], [infinity symbol])
If that last part confused you, ignore it because it means you just need to write all reals.
Pretty sure all of them have the same answer in this regard.
Range: y is greater than or equal to the last value in the equation.
For example: for 7 it would be y is greater than/equal to -6.
Translations:
4: shifted right 3
5: shifted down 7
6: shifted up 4
7:: left 1, down 6.
Any time you have an (x-n) n just being a letter I substituted for a number, the graph will be moved right n spaces from the origin. (x+n) moves it left.
If there are no parentheses, it means the graph is moved up or down, a minus indicating the graph being moved down by the number and a plus indicated it being moved up by the number.

Answer:
Last one.
Step-by-step explanation:
Answer:
a : b = 19 : 7
Step-by-step explanation:
Given
4a - 5b : 5a + 4b = 1 : 3
Expressing in fractional form, that is
= 
( cross- multiply )
3(4a - 5b) = 5a + 4b ← distribute left side
12a - 15b = 5a + 4b ( subtract 5a from both sides )
7a - 15b = 4b ( add 15b to both sides )
7a = 19b ( divide both sides by 7 )
a = 
b ( divide both sides by b )
=
That is a : b = 19 : 7
