Question

Consider the quadratic function f(x) = –2x2 + 4x + 2. Find the y-intercept and the equation of the axis of symmetry.1) The y-intercept is 2.The equation of the axis of symmetry is x = 1.2) The y-intercept is –2.The equation of the axis of symmetry is x = –1.3) The y-intercept is –1.The equation of the axis of symmetry is x = –2.4) The y-intercept is 1.The equation of the axis of symmetry is x = 2.

Answer 1

Given the function:

`f(x)=-2x^2+4x+2`

We will find the y-intercept of the function

The y-intercept is the value of (y) when (x = 0)

so, when x = 0

`f(x)=0+0+2=2`

so, the answer will be option 1)

1) The y-intercept is 2.

The equation of the axis of symmetry is x = 1.
