Domain and range of y = x2 + 9

Algebra Examples

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.

Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.

Domain:  

(−∞,∞),{x|x∈R}

Range:

[9,∞),{y|y≥9}

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

i hope this is what you were looking for.
