Question

1. Which equation represents the axis of symmetry of the function y = –2x² + 4x –6? (1 point)
y = 1
x = 1
x = 3
x = –3
btw this is for Algebra 1B unit 4 lesson 2
i already did the quick check but i want yall to get them right so the answers are below:)

Answer 1

1. B
2. A
3. D
4. B
5. D
6. B
7. D
8. C
Hope i helped :)

Answer 2

Well, it is a parabola and y goes to infinity as x gets large + or -
(opens upward)
let's see where the zeros are
Let me see where the zeros are
-2 x^2 + 4 x -6 = 0
x^2 - 2 x + 3 = 0
x = (2 +/- sqrt .... etc ) /2
x = 1 +/-sqrt ........
so symmetric about x = 1
