Question

What is leading coefficient of the function f(x) = 3x5 + 6x4 − x − 3?

a) 3

b) 4

c) 5

d) 6

Answer 1

f(x) = 3x⁵ + 6x⁴ - x - 3

The coefficient of a function f(x) is the number that multiplies the x with the highest exponent., that is 3. Answer a)

Answer 2

(A) 3

Explanation:

The given function is:

`f(x)=3x^5+6x^4-x-3`

Now, The leading term is the term containing the highest power of the variable and the leading coefficient is the coefficient of the leading term.

Thus, The leading term of the given function is
`3x^5`, therefore the leading coefficient is the coefficient of this leading term that is 3.

Hence,, option A is correct.
