Question

The graph of the function f(x)=-2x^2+6x-3 opens and has a value

Answer 1

Opens down

Maximum value

Answer 2

2x^2 +6x -3. if we are using the quadratic equation this would be

`- 6`

+ or -

`\sqrt{{6}^(2) - 4 * 2 * ( - 3) }`

all over 2×2

this simplifies to

`x = - (3)/(2) + ( √(15) )/(2)`

and

`x = - (3)/(2) - ( √(15) )/(2)`
