Use a graphing calculator to sketch the graph of the quadratic equation, and then state the domain and range y=2x^2-x+3

For the domain since we have a quadratic function then the domain would be all the real numbers:

And if we want to find the range we can find the vertex:

And now we can find th coordinate of y of the vertex like this:

And then the range would be:

Step-by-step explanation:

We have the following function given:

For this case we can plot the function with a calculator and we got the plot in the figure attached.

For the domain since we have a quadratic function then the domain would be all the real numbers:

And if we want to find the range we can find the vertex:

And now we can find th coordinate of y of the vertex like this:

And then the range would be:
