-3(y+2)2-5+6y
Steps
Multiply the numbers: 3 x 2 = 6
= -6(y + 2) - 5 + 6y
Then, expand - 6(y + 2): -6y - 12
= -6y - 12-5 + 6y
Simplify
-6y - 12 - 5 + 6y
= -17
2.4 is the right answer my guy
Answer:
A.This is the graph of the greatest integer function
E. f(-3.4)=-4
Step-by-step explanation:
The graph shown in the attachment is the parent greatest integer function.
f(x)=[x]
This takes any integer as an input and the output is the greatest integer less than the input.
For instance
f(4.9)=4 because 4 is the greatest integer less than 4.9
f(-3.4)=-4 because -4 is the greatest integer less than -3.4
This graph is not one-to-one because more x-values can correspond to one y-value.
For instance f(3.4)=3 and f(3.9)=3
The correct options are A and E
