The Edg answer is as follows -
The statement is not true for all real numbers. It is only true for decimal or fractional values of x .
If x is an integer, then the ceiling function returns x when the input is x . But, the flooring function returns x + 1 when the input is x + 1.
Since x does not equal x + 1 when x is an integer, the expressions are not equal when x is an integer.
Answer:
Step-by-step explanation:
f(x) = –2x² + 12x + 5
= -2 (x² - 6x - 5/2)
= - 2 ( x² -2(3)x +9 - 9 - 5/2)
= - 2 ( (x - 3)²-23/2)
f(x) = - 2 ( x - 3)²+23 .....vertex form
the vertex is : (3 : 23) Maximum at (3, 23) because a = -2 and a< 0
