The value of b is one. You just have to use the standard equation y = a + bx^2 + c. Get a, b, then c and from the given equation above you can derive a formula which is x is equal to the - b over 2 multiplied by a. if you get the value of x then substitute it to the equation and you will now get the value of b.
Answer: 25%
Step-by-step explanation:
F ( x ) = x² + 8 x - 6 = x² + 8 x + 16 - 16 - 6 =
= ( x + 4 )² - 22
Coordinates of the vertex : ( - 4, - 22 )
