Question

Does anyone know the answer

Answer 1

x = -
`(7)/(4)`

Explanation:

given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is

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

y = 2x² + 7x - 5 ← is in standard form

with a = 2 and b = 7 , then axis of symmetry is

x = -
`(7)/(2(2))` = -
`(7)/(4)` , that is

x = -
`(7)/(4)`
