Answer 1

Answer:

probably b

Step-by-step explanation:

I think for the other 3 answers, you are trying to have the x's have exponents, making them non-linear. While since b increases by 5 when x increases by 1, it is a linear function

Answer 2

Answer: The Answer Is (D.

Step-by-step explanation:

f(x) =

x

5

− 10

A function is linear if it can be expressed in the form f(x)= mx + b or if its graph is a straight line.

f(x)= mx + b

f(x) =

x

− 10

f(x) =
