i really need help with my work. I don't really get it. (1-3) 1. Determine the roots of function f(x)=2x-2x+1

2. (Has 3 parts) have to create a graph in order to answer the other parts

3. Write a quadratic function given the roots (-4,0) , and (2,0) and the point (4,4)

1. Determine the roots of the function f(x) = 2x2 - 2x + 1. 2. Is the graph of the function concave up or concave down? a) Analyze the function f(x) = 4x7 + 8x + 2. b) What is the y-intercept? c) What is the axis of symmetry? d) What is the vertex? 3. Write a quadratic function given the roots (-4, 0) and (2, 0) and the point (4, 4)
