The distributive property of 18(12), or simply 18 * 12, is 216. (This is your answer.)
Answer is B.) (-3,-3) and (2,7)
Here we will use exponential form, which is

Initial value, y0 = 500
Double of 500 = 1000



Required equation is

Subtract g(x) from f(x): (x²+3x-1)-(x³+4x²+1)=-x³-3x²+3x-2
C is the correct answer.
Use the sequence formula and the answer will be 981,090.
