Can you help me please?

Which of the following graphs could represent a cubic function?

Four equations are shown below.equation 1: y=2*equation 2: y=2x-5equation 3: y=x2 + 6equation 4: tdentify one linear equation and one nonlinear equation from the list.why each equation you identified is linear or nonlinear.nd one nonlinear equation from the list. state a reasonlinear equation

Which number completes the system of linear inequalities represented by the graph? y > 2x – 2 and x + 4y >
