CPM Homework Help : CCA2 Problem 1-90

Make a complete graph of the function $h(x)=2x^2+4x−6$ and describe its domain and range.

Hint:

Enter different $x$ -values into the equation and observe the behavior of the $y$ -values of the function, as well as the points on the graph.

More Help 1:

Is the graph symmetric? What is the line of symmetry? Is there a highest point? A lowest?

More Help 2:

For the domain, what possible $x$ -values can you enter into the equation?

More Help 3:

What is the smallest $y$ -value? Is there a largest? What is the range?

Use the eTool below to make a complete graph of the function.
