Here is the work if it is unclear:Â http://www.intervisualtechnology.us/data/1/13252/Unit_2_Quadratic_Functions_Unit_Project.pdf
Complete parts aÂc for each quadratic function.
a. Find the yÂintercept, the equation of the axis of symmetry, and the xÂ-coordinates of the vertex.
b. Make a table of values that includes the vertex.Â
c. Use the information to graph the function.
Â
f(x) = Â3x2 + 8x
f(x)=2x2 +7x+1
Determine whether each function has a maximum or minimum value. State the maximum or minimum value of each function.
f(x)=x2 +6x+9
f(x)=Âx2+4x
Write a quadratic equation with roots Â3 and 4 in standard form.
Solve each quadratic equation using the method of your choice. Find exact solutions.
Â1.6x2 Â3.2x+18=0
10x2 +3x=1
x2 +8xÂ48=0
Simplify the expression.
(5 Â 2i) Â (8 Â 11i)
(14 Â 5i)2
Write each equation in vertex form. Then identify the vertex, axis of symmetry, and direction of opening.

y=x2 +10x+27
y=Â9x2 +54xÂ8
Graph each inequality.
13. (xÂ5)(x+7)<0 14. Â5x2 +x+2<0
Find the exact solution to the system of equations. Check your answer algebraically.
y=x2 Â6x+1 y + 2x = 6
2x2 Â4x=y+1 x+y=1Â
