Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x + 2 intersect are the solutions of the equation 4x = 2x + 2.

Part B: Make tables to find the solution to 4x = 2x + 2. Take the integer values of x between -3 and 3.

Part C: How can you solve the equation 4x = 2x + 2 graphically?

At an intersection the functions equal each other.

anonymous · Answer

what ?

anonymous · Answer

Where they cross, they are equal, at that point.

He means when you graph a function and they intersect its when they are equal

anonymous · Answer

so for part a it would be because they are equal and it is a function ?
