Answer:
The function g(x) simply takes the value x and turns it into its reciprocal value . Thus, for instance, the number 5 becomes , and becomes 2. Note that any value of x works in this function as long as is defined. As mentioned, fractions work as well as whole numbers, both for positive and negative values; the only value that does not work is 0, since is undefined (how many times can 0 go into 1?). Thus, the domain of the function is all x in where x ≠ 0. Let's look at the graph of the function also.
Step-by-step explanation:
The function f simply takes in input value x, multiplies it by 2, and then adds 3 to the result. We can therefore consider what constitutes the set of numbers that the function can accept as an input and what constitutes the set of numbers that the function can yield as an output.
Answer:
Volume = 1436.8 cm³
Step-by-step explanation:
Formula for the volume of a sphere =
Here, r = radius of the sphere
For a sphere which has the radius = 7 cm
Volume of the sphere =
= 1436.76
≈ 1436.8 cm³
Therefore, volume of the sphere is 1436.8 cm³.
Just set it up like your average addition problem:
2x + y = 4
+ 3x - y = 6
then add one term at a time; work from left to right.
5x = 10 is your result. your y's cancel out.

Here ya go, enjoy my answer and good luck!
