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, ∞)

If you have ever swum in a pool and your eyes began to sting and turn red, you are aware of the effects on an incorrect pH level
RSB [31]
1. Create a graph of the pH function. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.
<span>The pH value is 1 at the orange dot, and is 1 at the red dot. </span>
<span>The transformation p(t+1) results in a y-intercept. </span>

<span>In this graph, the blue line is the original and first parent function p(t) = –log10 t. The pink line represent p(t) + 1, the transformation shifts up the y-axis by 1, but the p(t) + 1 transformation does not result in a y-intercept like the ones prior. The gold line represents p(t +1), which shifts horizontally by 1 to the left. This does result in a y-intercept, because the graph doesn't completely flip over the line to the other side, and the green line represents -1*p(t), which causes the graph to flip upside down, and doesn't end up as a y- intercept.</span>
