You have a typo in your answers or maybe there is an E. none of the above :)
Answer:
Given f(-2)
= -5 -7(-2)
= -5+14
= 9
Thus f(-2) of f(x)= 5-7x is 9
So than you check this graph so you see that the radius has a length of 4 units
from what result that thet x^2 +y^2 =4
so the choice 3rd is right sure
Remove the negative exponent by rewriting x^-3 as 1/x^3
(9)/(1/x^3)
multiply the numerator by the reciprocal of the denominator
9x^3
- b = c
