Let f(x) = 2x² + 12x + 1 a)
Find the coordinates of the vertex for this parabola. Is the vertex a maximum or a minimum? How do you know? Create a quick sketch of this function.
b) Use the difference quotient for this function to identify the approximate (or exact) value of x where the slope of f(x) is zero.
i) Find the DQ here.
ii) Find the value of x where slope = 0 here. ​
