Answer:
<em>As addition property of equality clearly states that if we add the same number to both sides of an equation, the sides remain equal.</em>
Step-by-step explanation:

Add x in both sides (Addition Property of Equality)

Multiply both sides by 2

Subtract 2x in both sides
∵adding both equation
divide both sides by 4

Put the value of y = 6 to the equation
Subtract 6 from both sides
Change the sign

Answer:
20
Step-by-step explanation:
f(x) = x + 10
Replace f(x) with y.
y = x + 10
Now, remember that in an inverse function you flip the x and y, so
x = y + 10
Solve for y
y = x - 10
because it's 2x... we must multiply by 2.
2y = 2x - 20
Original equation:
h(x) = 2x - 0
h(x) is 2y..

(a)The domain of the function is,
(b)The given function is discontinuous at x=0.
<h3>What is the domain and range of a function?</h3>
Domain is the set of values for which the given function is defined. Range is the set of all values which the given function can output.
The standard function is;

The domain of the given function is found as;

The domain of the function is,

To find the function is continuous or not, we have to find the continuity;

At x= 0 the function is undefined. So that the function is discontinuous at x=0.
Hence, The domain of the function is,
and the function is discontinuous at x=0.
