For your quadratic function you will need to find the optimal value remember that you can find this value by setting the quadratic function equal to zero and solving for the independent variable.

For Rebeccafrom SOF In this discussion board we need to come up with an example of a linear function and a quadratic function. For each function please define the domain (all possible input values for the independent variable) and range (all possible output values for the dependent variable). For your quadratic function you will need to find the optimal value; remember that you can find this value by setting the quadratic function equal to zero and solving for the independent variable.

Remember that a linear function has the following general form: y = f(x) = mx + b

and a quadratic function has the following general form: y = f(x) = ax2 + bx + c

I would also need one graph for each solution
