Question

Write a quadratic function in standard form that passes through (-8, 0), (-2, 0), and (-6,8).

f(x) =

Answer 1

-10xsquared-x+38

Explanation:

so,

general eqn of quadratic equation is,

axsquared+bx+c=y

where,

x and y are exchanged by coordinates given in qn

1,64a-8b+c=0

2,4a-2b+c=0

or c=2b-4a

60a-6b=0

3,36a-6b+c=8

32a-4b=8
