Question

This is long and complex, may you please get some help?

Answer 1

Answer:

Step-by-step explanation:

a = -4 , b = 16 and c = -17

$x =\dfrac{-b}{2a}\\\\x = \dfrac{-16}{2*(-4)}\\\\\\ =\dfrac{-16}{-8}$

x = 2

y = -4(2)² + 16*2 - 17

   = -4*4 + 32 - 17

   = -16 + 32 - 17

y = -1

Vertex (2, -1)

axis of symmetry: x = 2
