The function would be f(x)=11,500-.16xPlug in 4 for x
(a) Using the completing the square method, we need to write into the form of where , so
Expand to find the value of c
Notice that we get back the first two terms, the and the .We need to get rid of the last term of '9' as the term was not in the original form. The final form will look like
Hence,
(b)
(c) , square root both sides plus and minus of 2 Hence
× equals negative 4 i think and y equals -3
4 tenths and 2 hundredths is written .42
2 tenths and 4 hundreds is written .24
.42 is greater than .24
.42 > .24
Hope this helps.
