Find g(x), where g(x) is the reflection across the x-axis of f(x) = x?.

nignag [31]

Answer:

$g(x) = -x$

Step-by-step explanation:

The reflection of a function $f(x)$ along the $x - axis$ is given by $g(x) = -f(x)$ .

Here the given function is $f(x) = x$ . Therefore the reflection would be $g(x) = -x$ .

To find reflection draw the graph of it and think about how the graph of its mirror image would be. You would arrive at the reflection function.

Let

x-----> the number of sold pies

we know that

The inequality that represent the situation is

$4x\geq 200$

Solve for x

Divide by 4 both sides

$x\geq 200/4$

$x\geq 50\ pies$

The solution is the interval ------> [50,∞)

All positive whole numbers greater than or equal to 50

In a number line the solution is the shaded area at right of x=50 (close circle)

The Math Club must sell at least 50 pies to reach the goal
