Help please??

In your lab, a substance's temperature has been observed to follow the function T9x)=(x-2)^3+8. The turning point of the graph is where the substance changes from a solid to a liquid. Explain how to find the turning point of this function, using complete sentences.

@ybarrap ?? Again maybe?

OpenStudy (ybarrap):

So is your function $$ T(x)=(x-2)^3+8 $$ ?

OpenStudy (anonymous):

I guess

OpenStudy (ybarrap):

T(x) is a quadratic function. If that "2" wasn't there, you would have: $$ T(x)=x^2+8 $$ If that 8 wasn't there, you would have: $$ T(x)=x^2 $$ Do you know what \(x^2\) looks like?

OpenStudy (anonymous):

x*x ?

OpenStudy (ybarrap):

This is what it looks like: Notice it's just a curve and has a minimum at x=0. |dw:1385591375059:dw| But T(x)=(x-2)^2, this means that x^2 is shifted to the right, but has the same shape: |dw:1385591466998:dw|
