Need help with this geomtry problem asap

(05.03 mc) 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. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

What unit of been sure would be appropriate for the volume of a sphere with a radius of 2 meters
