Question

Find the axis of symmetry of the graph of

y = x2 + 2x + 2
A- x= 1
B- y=1
C- x= -1
D- y=-1​

Answer 1

Answer: x = -1

Explanation:

The formula to find the axis of symmetry in a function y = ax² + bx + c is:

`x=(-b)/(2a)`

For y = x² + 2x + 2, where:

• a = 1
• b = 2
• c = 2

The axis of symmetry would be:

`x=(-b)/(2a) =(-2)/(2(1)) =(-2)/(2) =-1`

Answer 2

x = -1

Explanation:

The graph's turning point is at ( -1 , 1 ), therefore the line of symmetry is at x = -1.
