2) The diagram below shows the graph of a quadratic function f(x) = -2x2 + bx + c. a) Write down the value of c. b) Find the value of b and write down f(x). c) Calculate the coordinates of the vertex of the graph of f​

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

What is the slope of the line shown below?
