Which function is linear?

A) f(x) = 3/2x + 1/2

B) f(x) = |3/2x| + 1/2

C) f(x) = (3/2x)^2 + 1/2

D) f(x) = 3/2x − 1/2

ok then what happened.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

4+3x hope you like mark as brainliest✔

just a girl thing, i think im cute when im not lol
