Parabola of the Form y=(x-p)²: True / false

To work out the points of intersection with the X axis, you must substitute $x=0$.

False

To find the y axis intercept, you substitute $x=0$ into the equation and solve for y.

True

$a$ is the coefficient $x^2$

Yes a>0 The function is maximum

Not true

To know whether the domain of a function is ascending or descending, you need to know the vertex point.

True.

The vertex of the function $y=x^2$ is the same vertex of the function $y=2x^2$.

True.

$y=(x+2)^2+2$

is a displacement of the function $y=(x+2)^2$.

False

$y=(x-4)^2$ is the displacement function $y=x^2$ right 4 steps

True

$y=(x+4)^2$ is the function $y=x^2$ moved left 4 spaces.

Yes
