Which equations below represent nonlinear functions?


y = 4x + 16


y = x2 − 2


34x − 9 = y


y = 7x


y = −8x


Answer :

Answer: y = x^2 - 2 does not represent a linear function because the squared exponent above the variable makes that equation quadratic. Quadratic equations look like parabolas on a graph, rather than lines.
