PilotLPTM [1.2K]

Answer:

$y-9=-\frac{3}{7} (x+4)$

Step-by-step explanation:

Slopes are negative reciprocals when two lines are perpendicular

$m= - \frac {3}{7}$

Equation of straight line in point-slope form is given as

$y-y_1=m(x-x_2)$

Here $(x_1, y_1)= (-4, 9)$

$y-9=-\frac{3}{7} (x+4)$

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)
