I'm really confused

Unit 4 - Day 5 assignment Name Period Estimate the graph of the following function and then give the specified information. (Hint: Find the vertex, Identify whether the equation is In vertex form, standard form, or both. axis of symmetry, and the y-intercept and use them to estimate your graph, just like yesterday's notes and homework). 1. /(x) -(x+2)3 -1 2. f (x ) = x-9 3. f(x) =-2x3-5x +3 9. f(x) = -x2 +4x +3 State whether the parabola opens up or down, has a maximum or a minimum, and also give the y-Intercept. 4. f(x) = -2x3+3x -1 5. f(x) = 6x2 + 7x 6. f(x) = =x - x+21 Opens UP or DOWN? Opens UP or DOWN? Opens UP or DOWN? Has a MAX or MIN? Has a MAX or MIN? Has a MAX or MIN? y-intercept: y-Intercept: y-intercept: Find the vertex of the quadratic function from the standard form of the quadratic function. Then give the remaining specified information. 7. f(x) = 3x+ 6x +4 8. f(x) =-2x- 12x +3 Vertex: Axis of Symmetry: y-intercept: Estimated x-intercepts: Opens UP or DOWN? Vertex: Vertex Vertex is MAX or MIN? Axis of Symmetry: Axis of Symmetry: Domain: Opens UP or DOWN? Opens UP or DOWN? Range: Vertex is MAX or MIN? Vertex is MAX or MIN? Domains Domain: Range Range: y-Intercept: y-intercept
