1 answer:
mr Goodwill [35]3 years ago
7 0

Answer:

x\geq 2

Step-by-step explanation:

we have

y=\sqrt{2x-4}

we know that

The radicand must be greater than or equal to zero

so

2x-4\geq 0

Solve for x

Adds 4 both sides

2x-4+4\geq 0+4

2x\geq 4

Divide by 2 both sides

x\geq 2

so

The domain is the interval for x ----> [2,∞)

All real numbers greater than or equal to 2

How do you translate the graph of f(x) = x3 left 4 units and down 2 units? Identify the equation of the graph
Marina CMI [18]

Answer:

The correct option is B.

Step-by-step explanation:

The given function is

f(x)=x^3

The translation of a function is defined as

g(x)=f(x+a)+b

If a>0, then the graph of f(x) shift a units left and if a<0, then the graph of f(x) shift a units right.

If b>0, then the graph of f(x) shift b units up and if b<0, then the graph of f(x) shift b units down.

It is given that the graph of f(x) shifts 4 units left and 2 units down.  So, a=4 and b=-2.

g(x)=f(x+4)+(-2)

g(x)=(x+4)^3-2              [\because f(x)=x^3]

y=(x+4)^3-2

Therefore option B is correct.
