Question

Graph the function $y=2\sqrt{x}+1$ and then state the domain and range of the function.

Step-by-Step Solution

Answer

The graph of the function $y=2\sqrt{x}+1$ is shown below whose domain is $\left[0,\infty \right)$ and range is$\left[1,\infty \right)$.

Step 1. Write down the given information.

The given function is $y=2\sqrt{x}+1$.

Step 2. Sketch the graph of given function.

The graph of the function $y=2\sqrt{x}+1$ is shown below.

Step 3. Interpretation from the graph.

From the graph, it can be interpreted that the domain of the function $y=2\sqrt{x}+1$ is $x\ge 0$ and range is $y\ge 1$.

Mathematically, domain $D_f\in \left[0,\infty \right)$ and range$R_f\in \left[1,\infty \right)$of the function$y=2\sqrt{x}+1$.
