well first we need to c in what places the no. 4s are
the 4 in the left is in the thousands place ....in numbers we can white it as 4,000
the 4 to the right is in the millions place .... in numbers we can white it as 4,000,000
so we can say that the one to the right is always greater .... 4 million ....
to find how many times its greater ... we of course need to subtract
4,000,000 - 4,000
= 3,996,000
range= biggest number - smallest number
1. m=1/2 b=4 y=1/2x+4
2. m=-1/2 b=-3 y=-1/2x-3
3. m=-3/2 b=-1 y=-3/2x-1
4. m=1/2 b=-1 y=1/2x-1
Answer:
Step-by-step explanation:
<u>Quadratic Function</u>
The quadratic function can be expressed in the following form:
Where a is a real number different from 0, and x1, x2 are the roots or zeroes of the function.
From the conditions stated in the problem, we know
x_1=1+\sqrt{2}, \ x_1=1-\sqrt{2}
Substitute in the general formula above:
Operate the indicated product
To find the value of a, we use the y-intercept which is the value of y when x=0, thus
It follows that
Thus, the required quadratic function is
Or, equivalently
