Using the triangle similarity postulates, you can verify that
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.

Answer:
Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.
Red =
Blue =
By graphing those equations, we can determine the solution(s)
The points where the graphs intersect would be your coordinates to derive your solution
Red = (1.864, 1.966)
Blue = (-0.427, 1.254)
The solutions would be the x-value of the ordered pair, in this case,
x = 1.864 AND x = -0.427
