Question 2

Type the letter of the function value next to its corresponding function and graph.

A
f(0)=0f of 0 equals 0

B
f(0)=0.5f of zero equals five tenths

C
f(0)f of zero does not exist.

1. f(x)=⌊x⌋f of x is a floor function

blank

2. f(x)=

2x+1,x<-negative4

-negative2x−1,x>2

f of x equals 2x plus 1 for x less than -4, and -2x minus 1 for x greater than 2

blank

3. f(x)=

2x+1,x<-negative0.5

-negative2x−1,x≥-negative0.5

f of x equals 2x plus 1 for x less than negative five tenths, and -2x minus 1 for x greater than or equal to negative five tenths.
