What type of number is -560,114? 1. whole number 2. integer 3. rational 4.irrational

2 and 3

Step-by-step explanation:

2 because integers are counting numbers (1,2,3,...) zero, and their opposites ( 1 and -1). 3 because a rational number is any number can be written is the form a/b where a and b are integers but b is not 0 ( i can explain this further) or is a decimal that either ends or has a repeated pattern

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
