4-151.

Shortcut Shuneel claims he has a short cut for finding the vertex of a parabola. While using his short cut on y = 2x2 + 3x +1, he ended up with . Is Shuneel correct? Why or why not? Homework Help ✎

Create x-y tables for each function and graph them.
Are they the same? If not, what is the difference?

$\text{Use algebra to rewrite }y =2\left( x - \frac{3}{4}\right)^{2} -\frac{7}{2}$

and compare it to Shuneel's original problem.

These are different functions, so unfortunately, Shortcut Shuneel's shortcut does not work.
The value of 'c' does not match up.
