what are the coefficients of 7x^4-9x^3+2x^2
1 answer:
In this case, whenever you see a number directly in front of x, multiplying itself by/with x, it's a coefficient.
That applies to the numbers 7, 9, and 2 if I'm reading this correctly. Hope this helps!

Answer:
a_n=125×20^(n-1)
Step-by-step explanation:
a_n=x×y^(n-1)
a_3=50000=x×y^2
a_5=20000000=x×y^4
y^2=20000000/50000=400
y=20;x=125
(4, -3).
Note that moving downward from the origin locates you in a negative y-cooirdinate; -3 in this case.
