Math Intercepts graphing Follow the steps below to graph the function f x 2x 4x 6 Sect Qu a Recall that if a 0 then the parabola will open up and if a 0 then the parabola will open down Identify a Will the parabola open up or open down b In College Algebra we saw that the vertex of a parabola can be found using the formula f Use the formula to find the vertex of the parabola Step 1 Find the x value x b 2a Step 2 Find the y value f just means to plug your x value you got above into your function to find the y value So take the x value you got and substitute it back in the original function to find the y value of the vertex y 2 4 6 Step 3 Use your x and y values to write the vertex as an ordered pair y intercept c Find the x and y intercepts Write your answers as ordered pairs x intercepts functions Let s try another function d Plot the vertex and intercepts and connect with a smooth curve to graph the function 10 08 61 4 2 10 8 6 4 2 N 4 4690 8 10 24 6 8 10
