Question

need step by step help,
The graph of y = ax 2 + bx + c passes through the points (-2, 0), (0, -2), and (2, 0). Determine the solution set of 0 = ax 2 + bx + c.

Answer 1

0=4a+2b+c ..... (1)
0=4a-2b+c ....... (2)
we can find that b=0

in (1)
0=4a+0+c
-2=c ..... (3)

(3) >> (2)
a=1/2

so the solution set is a =1/2; b=0; c=(-2)
^^

Answer 2

thanks(:
can you halp me with this one too?
\[-3/4x ^{2} +2\]

Answer 3

if the equation is written in general form, what is c?

Answer 4

c=2

Answer 5

okay, thank you so much:D
