1. Find the vertex. 2. Find the axis of symmetry,
3. Write the quadratic equation in vertex form.
a. Y = 2x? - 8x + 4
b. Y = -2x? - 10x + 6
c. Y = x2 - 2x - 3
d. Y = x2 + 6x + 8
e. Y = x?- 10x + 35

one of each metals

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
