In your lab, a substance's temperature has been observed to follow the function
T(x) = (x + 5)3 + 7. The turning point of the graph is where the substance changes from a liquid to a solid. Using complete sentences in your written answer, explain to your 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

Answer 1

This is gen vertex form where we can find the vertex. F(x) =a(x-h) + k
The vertex is (h,k)
Therefore, the vertex will be (-5,7)
