Question

which graph or graphs show a nonlinear function?

Answer 1

a) parabola \[y-k =4p (x-h)^{2} \]
b) line with positive slope (m)
\[y =mx + b\]
c)hyperbola with rotation
\[\frac{ (x-h) ^{2} }{ a ^{2} }-\frac{ (y-k)^{2} }{ b ^{2} }=1\]
d) line with negative slope(m)
\[y=-mx+b\]

Answer 2

notice: the equations are in the standard form
