Hurry i will fail math if i don't get this no joke

two numbers have a sum of 2 and a product of -8. the quadratic equation -n^2 + 2n + 8= 0 can be used to
determine the two numbers.

a) graph the related function f(n)= -n^8 +2n+8 and determine its x-intercepts

b) what are the two numbers?

for a you can just tell me the x intercepts

Liesl grew 7/12 of a foot in one year. her little sister grew 1/3 of a foot during that same year. how much more did liesl grow than her little sister did

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
