A. f(1)=5 (as defined on the second line, x=1) TRUE because f(1)=5
B. f(5)=5^2=25 (as defined on third line, x>1) FALSE because f(5) ≠ 1
C. f(-2)=2(-2)=-4 (as defined on first line, x<1) FALSE because f(-2) ≠ 4
D. f(2)=2^2=4 (as defined on third line, x>1) TRUE because f(2)=4
(-10+2)= -8 -8-1= -9 The answer is c
Just got this question from my teacher the answer is C I got 100 on the assignment
Option D is the correct answer.
When making a scale model, you need to ensure that both values are in proportion, or work with the same constant.
In the case of Option D, the scale model is '2 feet : 1 inch'. Since multiplying 11 by 2 is 22 and 12.5 by 2 is 25, you know for sure that these numbers are in proportion
