Answer:
Use the form a x^ 2 + b x + c , to find the values of a , b , and c .
a = 1 , b = 4 , c = − 5
Consider the vertex form of a parabola.
a ( x + d )^ 2 + e
Substitute the values of a and b into the formula d = b/ 2 a .
d = 4/ 2 ( 1 )
Cancel the common factor of 4 and 2 .
d = 2
Find the value of e using the formula e = c − b^ 2/ 4 a .
e = − 9
Substitute the values of a , d , and e into the vertex form a ( x + d )^ 2 + e .
( x + 2 )^ 2 − 9
Set y equal to the new right side.
y= ( x + 2 )^ 2 − 9
