Step-by-step explanation:

f(x)=-x²-2x-8 determine the vertex

Answers

Answer:

vertex = (- 1, - 7 )

Step-by-step explanation:

Given a parabola in standard form, f(x) = ax² + bx + c (a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = - x² - 2x - 8 ← is in standard form

with a = - 1 and b = - 2, then

[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{-2}[/tex] = - 1

Substitute x = - 1 into f(x) for corresponding y- coordinate

f(- 1) = - (- 1)² - 2(- 1) - 8 = - 1 + 2 - 8 = - 7

vertex = (- 1, - 7 )

For a quadratic function like this, the vertices are points of symmetry.
We can use a shortcut such that:
x

b

a

In your case,
b

a
is 1. So:

Which one is greater 26% or 0.3

Answers

Answer:

0.3 is greater

Step-by-step explanation:

The only way to compare these is to get them into the same format. Then, we will see which is larger. The way to convert a decimal to a percent is to move the decimal 2 places to the right.

0.3 = 30%

30% > 26%
