1. This is a linear function. Its graph is a straight line with a y, -intercept of , negative 4, and a slope of 10.
2. This is a nonlinear function. Its graph has a maximum at (0,10).
3. This is a nonlinear function. Its graph is a curve.
4. This is a linear function. Its graph is a straight line with a slope of −4 and a y-intercept of 10.
