Find the value of f(x) = [2.7] a. 2 b. 2.7 c. 3
1 answer:
The correct answer is A.
EXPLANATION
The given function is called the greatest integer function.
That is
f(x)=[x]
f(2.7)=[2.7]=2
The input is 2.7, the output
is the greatest integer that is less than or equal to 2.7
All integers less than 2.7 are
The greatest of all of them is 2.
In programming... The int variable behaves like this function.
int(2.7) will give you 2
Simply put that function gives you the integer part of whatever is in it.

A quadratic in vertex form can be represented as
a represents reflection over the x-axis, and a vertical stretch or compress
- is reflection and a fraction (1/2) represents a compression.
-h represents a shift of that many units to the right (-2 shifts to the right two units)
k represents a shift up or down (-2 is shifting down 2 units_
