Answer 1

Answer:

y - intercept is 3

Line of symmetry: x = -1

Step-by-step explanation:

y intercept is when x = 0

So it's 3

Line of symmetry of a quadratic:

x = -b/2a = -2a/2a

So, x = -1

Answer 2

Answer:

• y-intercept: (0, 3)
• axis of symmetry: x = -1

Step-by-step explanation:

The y-intercept is the constant, 3. It is the value of f(0).

__

The axis of symmetry of  the quadratic function ...

  f(x) = ax^2 +bx +c

is ...

  x = -b/(2a)

Here, using that formula gives ...

  x = -(2a)/(2(a)) = -1

The axis of symmetry is x = -1.
