Answer:
f(x)=8*(3.5)^x
Step-by-step explanation:
2=98
3= 98r
4= 98r^2
5= 98r^3
6= 98r^4
98r^4/98, 98 crosses out and its just r^4. r^4= 14706.125/98
r=3.5
So you plug that in and you get f(x)=8*(3.5)^x
I hope this helped. XD

Answer:
4/5
Step-by-step explanation:
you'd do 4 divided by 2 which is 2, then you'd do 10 divided by 2 which is 5. so you get 4/5.
the answer is X^3+6x<span>^2-7x+5
</span>

and you can expand the numerator if you wish, it won't be simplified further though.
Let me know if you need help with anything thanks
