If f(x) =3x2 and g(x)=4x3+1, what the degree of (f•g)(x)? 2 3 5 6

atroni [7]

f(x) = 3x²

g(x) = 4x³ + 1

f(g(x)) = 3.(4x³ + 1)²

As we know

(a + b)² = a² + 2.a.b + b²

So,

(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² = $4x^6+8x^3+1$

f(g(x)) = 3.( $4x^6+8x^3+1$ )

The degree is the maximum exponent, so, 6.

Order the ratios from least to greatest 16/24, 5 to 12, 6:13, 10:17, 13/28

saul85 [17]

Answer:

5/12, 6/13, 13/28, 10/17, 2/3

Step-by-step explanation:

First, simplify the ones that could be simplified.

2/3, 5 to 12, 6:13, 10:17, 13/28

(okay apparently only the first could be simplified)

You can look at all of them as fractions

2/3, 5/12, 6/13, 10/17, 13/28

Write a linear factorization of the function.

mart [117]

Answer:

f(x) = x^2 (x + 7i)(x - 7i)

Step-by-step explanation:

Factoring out x^2 gives ...

f(x) = x^2(x^2 +49)

The factor with 49 can be considered to be the difference of two squares, where one of the squares is -49. Then its square root is ±7i, and the factorization of that term is ...

x^2 +49 = (x +7i)(x -7i)

So, the overall factorization of f(x) is ...

f(x) = x^2(x +7i)(x -7i)
