Question

What is the axis of symmetry for f(x) = 2x2 + 4x + 2?

Choices
x = −3

x = −1

x = 1

x = 3

Answer 1

-1

Explanation:

to find the axis of symmetry, the formula is X= -b/ 2a

a is the 2 from 2x2

and b is 4 from 4x

then plug them to the formula

-b= -4 because of the negative in -b

and 2a is 2(2)

-4/4 is -1

so x= -1

hope im right

hope it helps
