Answer:

To write a polynomial function in standard form that has a zero at 4 with a multiplicity of 3 and a zero at 0 with a multiplicity of 1, we can use the concept of polynomial factorization.

Given:

Zero at 4 with multiplicity 3

Zero at 0 with multiplicity 1

To represent this function, we can start with the linear factors:

(x - 4)(x - 4)(x - 4)(x - 0)

Simplifying the factors, we have:

(x - 4)^3(x - 0)

Expanding further:

(x - 4)(x - 4)(x - 4)x

Now, let's multiply the factors to obtain the polynomial in standard form:

(x - 4)(x - 4)(x - 4)x = (x^3 - 12x^2 + 48x - 64)x

Multiplying, we get:

x^4 - 12x^3 + 48x^2 - 64x

Therefore, the polynomial function in standard form that represents the given conditions is:

f(x) = x^4 - 12x^3 + 48x^2 - 64x.

Explanation:

To write a polynomial function in standard form that has a zero at 4 with a multiplicity of 3 and a zero at 0 with a multiplicity of 1, we can use the zero-product property and the fact that if a zero has a multiplicity greater than 1, the corresponding linear factor appears multiple times.

Given:

Zero at 4 with multiplicity 3

Zero at 0 with multiplicity 1

To represent this function, we can start with the linear factors:

(x - 4)(x - 4)(x - 4)(x - 0)

Expanding this expression, we have:

(x - 4)^3(x - 0)

Now, let's simplify and rewrite it in standard form:

(x - 4)^3(x)

Expanding further:

(x - 4)(x - 4)(x - 4)x

Finally, let's multiply the factors to obtain the polynomial in standard form:

(x^3 - 12x^2 + 48x - 64)x

Multiplying, we get:

x^4 - 12x^3 + 48x^2 - 64x

Therefore, the polynomial function in standard form that represents the given conditions is:

f(x) = x^4 - 12x^3 + 48x^2 - 64x.
