What are the domain and range of g of x equals the square root of the quantity x plus 4?
boyakko [2]

Using it's concept, it is found that the domain and range of the function are given by:

D: [–4, ∞) and R: [0, ∞)

<h3>What are the domain and the range of a function?</h3>
  • The domain of a function is the set that contains all the values of the input.
  • The range of a function is the set that contains all the values of the output.

In this problem, the function is:

g(x) = \sqrt{x + 4}

The square root function does not exist for negative values, hence the domain is represented by:

x + 4 \geq 0 \rightarrow x \geq -4

The range of the square root function is x \geq 0, which remains the same as there are no vertical translations.

Hence the correct option is given by:

D: [–4, ∞) and R: [0, ∞)

HELPPPPPPPPPPPPPPP PLEASEEEEEEEEEEEEE!!!!!!!!!!!11
mr_godi [17]

To find the perimeter, the equation is (w2 + l2 = p)

Where w is width and l is length and p is perimeter.

If you have the width, then you double it for both widths.

Then subtract that number from the perimeter.

150-60 = 90

90 is the remaining number for the lengths. Since both lengths needs to be equal, you split the 90. 45.

You length equals 45.

45(2) + 30(2) = Perimeter of 150.

Your answer is 45.

Solve the system by substitution.<br> y = -9x<br> y = 2x + 33
Gwar [14]

Answer:

y =  - 9x \\ theny = 2x + 33 \\  - 9x = 2x + 33 \\  - 9x - 2x = 33 \\  - 11x = 33 \\ x =  \frac{ - 33}{11}  =  - 3 \\ x =  - 3 \\then\\ y=-9×-3=21\\ thank \: you
