If you want to expand it, here it is: -6x^2-12-14x-28, which is equal to -6x^2-26-28. Thank you so much to the person that corrected me! Hope this helped! A brainliest is always appreciated.

Expand by FOILing.  Doing that gives you -6 x^{2} -12x-14x-28, which, when simplified, is -6 x^{2} -26x-28.  An equivalent way to represent this is to change all the signs so the leading coefficient is not negative.  6 x^{2} +26x+28

Write the relation below as a set of ordered pairs and state if it is a function. If it is not a function, explain why.
AleksAgata [21]
This is a linear function. Let diameter (inches) be x, circumference (inches) be y, observe that the value of y/x is always 3.14. For example, 15.7/5=31.4/10=...=3.14. Therefore, this is not only a function (one to one correspondence from x to y), it's also a linear function that can be represented as y=3.14x.
