What is the equation of the following graph?

The given graph represents a downward parabola with centre (h,k) = (2,-4) and it passes through (8,-7) .

Here we use the following formula

So the required equation is

or

2

step-by-2step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
