Which of the following represents a Linear function?

A. y= 3x²+2
B. y= 2x²-7
C. y= 2x+2
D. y= 3x³-7

C

Step-by-step explanation:

any function of first degree represents a linear function.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
