Question

I need help with this

Answer 1

x = - 4

Explanation:

Given a parabola in standard form

f(x) = ax² + bx + c ( a ≠ 0 )

Then the equation of the axis of symmetry is

x = -
`(b)/(2a)`

f(x) = 2x² + 16x - 19 ← is in standard form

with a = 2, b = 16

Then the equation of the axis of symmetry is

x = -
`(16)/(4)` = - 4
