Answer:

Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1

Step-by-step explanation:

What are the vertex and axis of symmetry of the equation?

The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

Answer:

$f(x+h)=x^2+2xh+h^2+2x+2h$

Option D is correct option.

Step-by-step explanation:

We are given: $f(x)=x^2+2x$

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

$f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h$

Finding f(x+h) we get:

$f(x+h)=x^2+2xh+h^2+2x+2h$

Option D is correct option.

asambeis [7]

Answer:

200 units.

10 minutes.

Step-by-step explanation:

Distance = 100 - (-100)

= 100 + 100

= 200 units.

Speed = distance / time

20 = 200/ t

t = 200/20

= 10 minutes.
