Write the equation for the graphed function. I worked out y = 5 - 4 (x + 4)^2 but that isn't right. Any help would be appreciate
alexira [117]

Vertex form for a parabola with vertex (p,q) is

y = a(x-p)^2 + q

We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>

2 = a(-3 - -4)^2 + 5

2 = a + 5

a = -3

Putting it together,

Answer: y = -3(x + 4)^2 + 5

We could multiply that out if we like but I won't bother.

Rafeal wants to know if there is a single transformation that will move trapezoid JKLM onto trapezoid PQRS Below
aliina [53]

A. A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R.

Step-by-step explanation:

Since both the trapezoids, trapezoid JKLM and PQRS are congruent, we can do any transformation, may be rotation, reflection and translation.

A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R is the true statement others are incorrect statements.

When the Preimage is rotated 90° counterclockwise rotation, then its coordinates (x,y) changed into (-y,x)
