In order for a function to have an inverse that is also a function there are 2 main requirements:
1. The function should be bijective (ie) the function should be one-one ( each element in codomain has not more than 1 pre image in domain) and onto ( Range should be equal to codomain)
2. The inverse function should be defined by a suitable domain and range

Answer:
If each vertical line passes through only one point, it is a function.
Step-by-step explanation:
The algebraic equation for the line whose slope is m = 1 and passes through point (3 , 3) is y = x
Step-by-step explanation:
The algebraic equation of a line whose slope is m and passes
through point is
- This form is the slope-point form of the equation of a line
∵ The slope of the line is m = 1
∵ The line passes through point (3 , 3)
∴ = 3
∴ = 3
- Substitute these values in the form of the equation
∵
∴ y - 3 = (1)(x - 3)
- Simplify it
∴ y - 3 = x - 3
- Add 3 to both sides
∴ y = x
The algebraic equation for the line whose slope is m = 1 and passes through point (3 , 3) is y = x

Answer:
-1
Step-by-step explanation:
by collecting like terms
-17h -4h -2h = 19+4
-23h = 23( divide both sides by coed. of h)
h= -1
