What are the domain and range of the function x^2-2x^2-4?
jonny [76]

{x}^{2}  - 2 {x}^{2}  - 4 \\  -  {x}^{2}  - 4

The Quadratic Function has the domain as the set of all real numbers.

For the range, start from minimum value to maximum value.

But because the parabola is downward as a < 0. Thus, there are no minimum value but the maximum value instead.

Therefore the range is y <= -4

If M is between S and T, SM = 9x - 8,<br> MT = 2x + 3, and ST = 72. Find x.
kolezko [41]

Answer:

7

Step-by-step explanation:

Since, M is between S and T.

Therefore, SM + MT = ST

9x- 8 + 2x + 3 = 72

11x - 5 = 72

11x = 72 + 5

11x = 77

x = 77/11

x = 7
