What is true of the function g(x) = -2x² + 5?
Dafna1 [17]

Answer:

C.) The variable x represents the independent variable

Step-by-step explanation:

The variable "x" is the independent variable because that is the value that we can manipulate. We cannot manipulate the dependent variable because it is determined by the independent variable. In that case, "y" would be the dependent variable because its value is dependent on what "x" is.

A.) is incorrect because g(x) symbolizes the input of the variable "x" into the g function.

B.) is incorrect because "x" is the input.

D.) is incorrect because "x" is the input.

What are all the digits of pie?
Artemon [7]

'Pi' is an irrational number.  It can never be completely written with digits.

Here are the first 15 decimal places:    3.14159 26535 89792

A supercomputer lab in Japan has calculated <u>4 trillion</u> digits of pi,
and it still doesn't end. 

With higher mathematics, it's possible to <u>prove</u> that pi never ends.
So, no matter how many digits somebody gives you for pi, there are
still an infinite number more after those.
