Binomial Theorem · Exercise 43

Use the Binomial Theorem to expand the binomial $f\left(x\right)={\left(x+3\right)}^4.$ Then find and graph each indicated sum on one set of axes.

Find and graph $f_1\left(x\right),$ such that $f_1\left(x\right)$ is the first term of the expansion.

Its source prints no answer for this problem, so there's nothing to check against.
