Answer:
Given the function:
The rule of reflection across the x-axis is given by:
Apply the reflection over the x-axis on the given function we have;
Multiply both sides by -1 we get;
or
Therefore, function represents a reflection f(x)=3/7(2)^x over the x-axis is,
ANSWER
Therefore the correct answer is B
<u>EXPLANATION</u>
The equation in the point slope form of a straight line is given by the formula;
, where
is the slope and the point
is any point on the line.
Since two points on the line are given, Lamont must find the slope using the points and
as follows;
.
He can now choose one of the points as .
If he uses , the he obtains,
Which gives as the equation of the line.
Therefore the correct answer is B
