Micah found the vertex for the function y= -9.5x? 47.5x+ 63 as shown. Find and correct Micah's error. Explain the error?

See Explanation

Step-by-step explanation:

The question is incomplete as Micah's workings is not attached. So, there's no way to determine where Micah's error is.

However, I'll solve for the vertex of the given function.

Given

Vertex, V is of the form:

Where

and

Solving for h:

So:

Solving for k

Substitute 2.5 for x in

Hence:

The vertex is

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
