X+2=x to the second power +4 at x = 2

Mathematics

serg [7]3 years ago

No it doesn't.

When x=2,

                          x + 2  =  4
and
           x² + 4  =  4 + 4  =  8

If you want  (x + 2) to be equal to  (x² + 4),
then

either    x = 0.5 + 1.323 i
or               
             x = 0.5 - 1.323 i  .            ' i ' = √-1
                                                
There are no other ways to do it.

1. Graph the function g(x) = [X1 + 4 as a translation of the
Elenna [48]

Answer:

The translation did not effect the domain

The translation effected the range

Step-by-step explanation:

The given graph represents f(x) = IxI

The domain of f(x) is {x : x ∈ R}, where R is the set of real numbers

The range of f(x) is {y : y ≥ 0}

The graph of g(x) is attached down

g(x) = IxI + 4

The domain of g(x) is {x : x ∈ R}, where R is the set of real numbers

The range of g(x) is {y : y ≥ 4}

The graph of g(x) is the image of the graph of f(x) after translate it 4 units up

∵ The translation is vertically

∴ The domain of f(x) = the domain of g(x)

∵ The domain of f(x) is {x : x ∈ R}

∴ The domain of g(x) is {x : x ∈ R}

∴ The translation did not effect the domain

∵ g(x) = f(x) + 4

∵ The range of f(x) is {y : y ≥ 0}

- Add 4 to the value 0

∴ The range of g(x) is {y : y ≥ 0 + 4}

∴ The range of g(x) is {y : y ≥ 4}

∴ The range of g(x) not equal the range of f(x)

∴ The translation effected the range
