Question Which function is linear? A) f(x)=8x2+2f(x)=8x^2+2, B) f(x)=8x+2f(x)=\frac{8}{x}+2, C) f(x)=8x22f(x)=8x^2-2, D) f(x)=x82f(x)=\frac{x}{8}-2

Studdy Solution
Conclude that option D is a linear function because it is of the form f(x)=mx+bf(x) = mx + b, where m=18m = \frac{1}{8} and b=2b = -2.
The function that is linear is option D, f(x)=x82f(x) = \frac{x}{8} - 2.
