The vertex and the t-intercept where t>0, will help solve this problem. Sending the work on the attachment.
Step-by-step explanation:
Use this algebra 2 theorem:
If r and q are roots of a polynomial function then
the polynomial function can be expressed as
Here the roots are
1- root of 6, 1+ root 6, and. 7-i so our. function can be expressed as
The first two binomials are difference off squares so the we have
The other root is (7-i).
Also note since (7-i) is a root, then (7+I) is also a root.
So
Simplify and it gives us
<span>Two problems such as 150,000 + 150,000 = 300,001 and 500,000 - 200,000 = 300,000 could show that two problems can give the same result. A third could be 400,000 - 148,000 = 252,000 but rounds to 300,000 when rounded. All three give the same result when rounded to the nearest hundred thousand.</span>
