Question

Which of the following is a linear function?

y = 3x to the power of 2
y = 1 over 3x
y = x to the power of 3 + 5
2 over 3x = y − 1

Answer 1

y= 1 over 3x

Explanation:

I thought it was 2 over 3x but it was wrong so it has to be y= 1 over 3x

Answer 2

Both B and D can be linear functions, as a linear function follows the format

y = mx + b

And both B and D can be linear functions.

B can be y = 1/3x

and D can be y = 2/3x + 1
