The function f(x) = (x − 4)(x − 2) is shown. what is the range of the function? all real numbers less than or equal to 3 all real numbers less than or equal to −1 all real numbers greater than or equal to 3 all real numbers greater than or equal to −1

This parabola y=f(x) = (x²-6x+8) is:

1) Open downward (a>0)

2) it's axis of symmetry = -b/2a = 62 = 3

3) for x=3 , y= -1, So its minimum is at (3,-1)

4) Since its minimum is at y=-1, so it cannot go below -1

5) So its range is {y∈R: y>= - 1}

or all real numbers greater than or equal to −1

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

The slope of the function is 0.5.
