How do I find the quadratic equation with the following: passing through (1/2,0), (-1/2,0), and (0,1) ??

Step-by-step explanation:

passing through (¹/₂,0) and (-¹/₂,0) so:  ¹/₂ and -¹/₂ are roots of the equation

so:

     y = a(x - ¹/₂)(x-(-¹/₂))

     y = a(x - ¹/₂)(x +¹/₂)

     y = a(x² - ¹/₄)

and passing through (0,1) so:

     1 = a(0² - ¹/₄)

     1 = - ¹/₄a

     a = -4

therefore:

                 y = 4(x² - ¹/₄)

                 y = 4x² - 1

So the quadratic equation:   4x² - 1 = 0

x/3-10=8

x/3=18

x=48

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
