Which function is a quadratic function? a(x) = –2x3 + 2x – 6 b(x) = 5x3 + 8x2 + 3 c(x) = –8x2 + 3x – 5 d(x) = 6x4 + 2x – 3

Every time you drive you will experience a combination of driving conditions and environments.

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
