Find the range for the following quadratic function.

Answer explanation

To solve this problem, you can enter the ENTIRE table into desmos. Then you use the standard form of a quadratic equation to find the vertex. The y-value of the vertex gives you the value of the range.

Answer explanation

You need to factor these first to get (x+18)(x-3). Then you set each of these factors equal to 0 and solve for the value of x. So x+18 = 0 and x-3=0. When you solve you get x = -18 and x = 3
