Which function is linear? a) f(x) = 8x2 + 2 b) f(x) = 8 x + 2 c) f(x) = 8x2 − 2 d) f(x) = x 8 − 2

Answer with Step-by-step explanation:

A linear function is of the form ax+b

A) f(x) = 8x² + 2

The above expression is not of the form ax+b

hence, it is not linear

B) f(x) = 8 x + 2

The above expression is of the form ax+b

hence, it is linear

C)f(x) = 8x² − 2

The above expression is not of the form ax+b

hence, it is not linear

D) f(x) =

The above expression is not of the form ax+b

hence, it is not linear

Hence, function which is linear is:

B)f(x) = 8 x + 2
