Question

PLEASE HELP ME!
What is the x-coordinate where the graph of the function represented by the Maclaurin series 1 minus 2 times x plus 4 times x squared over 2 factorial minus 8 times x cubed over 3 factorial plus dot, dot, dot, negative 1 raised to the nth power times 2 to the nth power times n to the nth power over n factorial plus dot, dot, dot intersects the graph of y = x3 ? (5 points)

0.649
1.000
0.865
0.773

Answer 1

I do not have the slightest idea what your question is saying but try each of the solutions and see if one of them works.

Answer 2

The series is just e^(-2x)
so, e^(-2x) = x^3
when x = 0.6488
