). Her work is shown.
Which best describes the FIRST error in Jan'ai's work?
A) She incorrectly determined the factors for the beginning function.
B) She incorrectly determined the a value.
C) She incorrectly transformed the equation to standard form.
D) She incorrectly determined the x-coordinate of the vertex.
I think it is C idk tho
