Step-by-step explanation:</h2>
Multiplication is when you have a number that you need to multiply by that number. Okay, let me give you an example:
2x4 means = 2+2+2+2 or 4+4
3x6 means = 3+3+3+3+3+3 or 6+6+6
the answer will always be the same.
GOOD LUCK !! :)

Equation of a parabola with vertex at (2, -1) is
y = a(x - 2)^2 - 1
Using the given point: -3 = a(4 - 2)^2 - 1
-2 = a(2)^2
4a = -2
a = -1/2
Therefore, required equation is
y = -1/2(x - 2)^2 - 1
y = -1/2(x^2 - 4x + 4) - 1
y = -1/2x^2 + 2x - 2 - 1
y = -1/2x^2 + 2x - 3
