Describe in words and symbols the end behavior of f(x)=−5x4

The graph is attached below.

Step-by-step explanation:

Given the function

Since the leading term of the polynomial (the term in a polynomial that contains the highest power of the variable) is -5x⁴,  then the degree is 4, i.e. even, and the leading coefficient is -5, i.e. negative.

This means that f(x) → −∞  as x → −∞ and f(x)→−∞  as x→∞.

The graph is attached below.

-16a+24b-30b+20a

(-16a+20a)+(24b-30b)

THE ANSWER IS 4A-6B
