Question

given t(z) = 2z^2 -4z + 6 determine t(-6)

Answer 1

just plug in -6 for z

Answer 2

@cardinal_carlo okay thanks and how would I solve this one...
Find the axis of symmetry of the functions graph f(x) = 2x^2 + 20x+ 46

Answer 3

First, let's find the vertex.
\[f'(x) = 4x + 20\]\[~~~~~~~0 = 4x + 20\]\[~ -20 = 4x\]\[~~-5 = x\]

Alright, the axis of symmetry of f(x) = 2x^2 + 20x+ 46 is x = -5.

Answer 4

@cardinal_carlo I got -4. Thank you so much btw
