Please help with this I am completely stuck on it

Answer:

$f(x)=\sqrt[3]{x-4} , g(x)=6x^{2}\textrm{ or }f(x)=\sqrt[3]{x},g(x)=6x^{2} -4$

Step-by-step explanation:

Given:

The function, $H(x)=\sqrt[3]{6x^{2}-4}$

Solution 1:

Let $f(x)=\sqrt[3]{x}$

If $f(g(x))=H(x)=\sqrt[3]{6x^{2}-4}$ , then,

$\sqrt[3]{g(x)} =\sqrt[3]{6x^{2}-4}\\g(x)=6x^{2}-4$

Solution 2:

Let $f(x)=\sqrt[3]{x-4}$ . Then,

$f(g(x))=H(x)=\sqrt[3]{6x^{2}-4}\\\sqrt[3]{g(x)-4}=\sqrt[3]{6x^{2}-4} \\g(x)-4=6x^{2}-4\\g(x)=6x^{2}$

Similarly, there can be many solutions.

What is 2A?<br> A= [4 9 13 5]

Ierofanga [76]

Answer:

Multiply each entry by 2!

Step-by-step explanation:

Multiplying a matrix by a constant means to multiply each entry by that constant.

According to that, 2A would be the result of each entry being multiplied by 2.

That is equal to $$ 2A = \begin{pmatrix}2(4) & 2(9) \\2(13) & 2(5) \\\end{pmatrix}$

$$ \implies 2A = \begin{pmatrix}8 & 18 \\26 & 10 \\\end{pmatrix}$

Hence, the answer.
