Identify the restrictions on the domain of f(x) = quantity x plus 5 over quantity x minus 2.

For this case we must find the domain of the following function:

By definition, the domain of a function is given by all the values for which the function is defined. The given function is not defined when the denominator is zero, that is:

Thus, the domain of the function is given by real numbers except 2.

All real numbers except 2

step-by-step

the area of the piece of paper =   27- inch square.

so, the length of the square piece of paper = = .

the side of the triangle cut = =

also the side of the small square cut =

so, the area of each triangle cut = 1/2 * .

so, the area of 4 triangles cut =

area of a small square cut =

total area of 4 triangles cut and a small square cut = 6+3 = 9 square inches.

reaming area of the octagonal window   = 27 - 9 = 18 square inches.
