Determine the total number of roots of each polynomial function f(x)=3x^6+2x^5+x4-2x^3

Alisiya [41]

Answer:

6 roots

Step-by-step explanation:

f(x)=3x^6+2x^5+x4-2x^3

The number of roots is determined by the degree of the polynomial. They may be real or complex.

Since this is a 6th degree polynomial, it will have 6 roots

f(x)=3x^6+2x^5+x4-2x^3

1) f(x) = 2x + 4, g(x) = 4x2 + 1; Find (g ∘ f)(0).

Sholpan [36]

Answer:

<h2> $(g \: \circ \: f)(0) = 17$ </h2>

Step-by-step explanation:

f(x) = 2x + 4

g(x) = 4x² + 1

In order to find (g ∘ f)(0) we must first find

(g ° f )(x)

To find (g ° f )(x) substitute f(x) into g(x) that's for every x in g(x) replace it with f(x)

That's

<h3> $(g \: \circ \: f)(x) = 4( ({2x + 4})^{2} ) + 1 \\ = 4(4 {x}^{2} + 16x + 16) + 1 \\ = {16x}^{2} + 64x + 16 + 1$ </h3>

We have

<h3> $(g \: \circ \: f)(x) = {16x}^{2} + 64x + 17 \\$ </h3>

Now to find (g ∘ f)(0) substitute the value of x that's 0 into (g ∘ f)(0)

We have

<h3> $(g \: \circ \: f)(0) = 16( {0})^{2} + 64(0) + 17 \\$ </h3>

We have the final answer as

<h3> $(g \: \circ \: f)(0) = 17$ </h3>

Hope this helps you
