7 0

<u>Answer:</u>

f ( 2 x ) = 4 x ^ 2 - 8

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify the given function:

f ( x ) = x ^ 2 - 8

Applying the function f(2x) on f ( x ) = x ^ 2 - 8 to get:

f ( 2 x ) = ( 2 x ) ^ 2 - 8

f ( 2 x ) = 4 x ^ 2 - 8

The points (–2, 4) and (–2, –2) are vertices of a heptagon. Explain how to find the length of the segment formed by these endpoi
Scrat [10]

Answer:

The segment is 6 units long.

Step-by-step explanation:

The points (–2, 4) and (–2, –2) are vertices of a heptagon. We have to explain how to find the length of the segment formed by these endpoints.

If two points at the ends of a straight line PQ are P(x_{1},y_{1}) and Q(x_{2},y_{2}), then the length of the segment PQ will be given by the formula  

\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}}

Now, in our case the two points are (-2,4) and (-2,-2) and the length of the segment will be  

\sqrt{(- 2 - (- 2))^{2} + (4 - (- 2))^{2}} = 6 units. (Answer)
