Find the vertex and axis of symmetry for f(x)=2x^2-1

vfiekz [6]

<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>

Solution:

Given is:

$f(x) = 2x^2 - 1$

We have to find the vertex and axis of symmetry

The general equation is given as:

$f(x) = ax^2 + bx + c$

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

$x = \frac{-b}{2a}$

$x = \frac{0}{2(2)}\\\\x = 0$

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

$f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1$

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)

What is the value of x?

Ray Of Light [21]

96 and (6x - 36) are alternate exterior angles, meaning that they are equal to each other.

6x - 36 = 96

Add 36 to both sides.

6x = 132

Divide by 6 on both sides.

x = 22

The value of x is 22.

Round 74.141 to the nearest tenth

user100 [1]

Hi!

The number in the tenth place, is 74.141.
Look at the number to the right of the one, is it higher or lower than 5?
It lower than five, so we round down.

<h2>The answer is 74.1</h2>

Hope this helps! :)
