In your lab, a substance's temperature has been observed to follow the function T(x = (x- 4)° + 6. The turning point of the graph is where the substance changes from a

fellow scientists how to find the turning point of this function. Hint: The turning
point of the graph is similar to the vertex of a quadratic function. (10 points)
