Which function represents g(x), a reflection of f(x) = } (10)* across the x-axis?
O g(x) = - (10)*
O g(x) = -(0)
O g(x) = (10)
O g(x) = { (10)*

Step-by-step explanation:

For a general function f(x), a reflection across the x-axis is written as:

g(x) = -f(x)

So, if here the function is:

The reflection across the x-axis is:

The correct option is the first one, counting from the top.

-4

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
