Step 1

As per our policy I am solving 1st three subparts and for the remaining subparts post the question again separately.

Given,

Step 2

Part a help_outlineImage Transcriptionclose3x2 + 6x - 1 f (x) -3(x2 — 2х) — 1 3(x2 2x 1 - 1) 1 (adding and subtracting 1) - -3((x -1)2 -1) -1 — — 3 (х — 1)2 + 3 — 1 — — 3 (х — 1)2 + 2 So, the vertex form of f(x) is -3(x -1)2 2 and vertex of f(x) is (1,2) fullscreen
