Answer:

c or d

Step-by-step explanation:

B- f(x) = (x + 1)/x = 1 + 1/x the order of variable x is (1), not one, so it's not Linear

(A function is linear implies that it's a constant or a first-order polynomial

C f(x)=7x-2.i75 a first-order polynomial with respect to X. So it's Linear. D. f(x) = 3x + 4 it's a first-order polynomial with respect to X. So it's Lincar

function)

Solution

A f(x) = 2x ^ 2 + 1 the order of variable x is two, not one. so it's not linear.
