Question

Solve pretty please with cherries on top <3

Answer 1

The Correct answer is D

(-1,-5)

Answer 2

D

Explanation:

given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

then the x- coordinate of the turning point ( vertex ) is

`x_(vertex)` = -
`(b)/(2a)`

y = 2x² + 4x - 3 ← is in standard form

with a = 2, b = 4 , then

`x_(vertex)` = -
`(4)/(2(2))` = -
`(4)/(4)` = - 1

substitute x = - 1 into the equation for corresponding y- coordinate

y = 2(- 1)² + 4(- 1) - 3 = 2(1) - 4 - 3 = 2 - 7 = - 5

turning point = (- 1, - 5 )
