Answer:

Step-by-step explanation:

(f • g)(x)

= f(x) × g(x)

= (x + 4)(3x² - 7)

each term in the second factor is multiplied by each term in the first factor , that is

x(3x² - 7) + 4(3x² - 7) ← distribute both parenthesis

= 3x³ - 7x + 12x² - 28

= 3x³ + 12x² - 7x - 28 ← in standard form

The value k needed for the transformation of f(x) to g(x) = f(k · x) is equal to 3.056.

<h3>How to find the find the dilation factor</h3>

In this problem we have the following relationship bewteen the two <em>quadratic</em> equations: g(x) = f(k · x), which means that for all y the following relationship between f(x) and g(x):

$k = \frac{x_{g}}{x_{f}}$

Let suppose that y = 3, then $x_{f} = - 5.5$ and $x_{g} = - 1.8$ , then the value k is:

k = (- 5.5)/(- 1.8)

k = 3.056

The value k needed for the transformation of f(x) to g(x) = f(k · x) is equal to 3.056.

Q1. If ∛5x+10=5, Find x

aleksandrvk [35]

Answer:

$\sqrt[3]{5x+10}=5 / ^{3}\\ 5x+10=125\\5x=115/:5\\x=23$

If you mean that : $\sqrt[3]{5x}+10=5$ this is

$\sqrt[3]{5x}+10=5 /^{3} \\5x+1000=125\\5x=-875/:5\\x=-175$
