A)
f(x) = 8x² + 2
B)
8
f(x) -
X
+ 2
f(x) - 8x? - 2
D)
f(x) = -2

Answer 1

B)

Explanation:

Assuming the numbers following the variables are exponents, (ex: 8x2, x8), the only function that is linear would be option B. This is because linear functions do not have exponents following their variables. If graphed, t are a straight line.
