Answer:

Step-by-step explanation:

To find inverse:

replace f(x) with y: y = 2(x + 4)

Then switch y and x: x = 2(y + 4)

Finally make y the subject:

x = 2(y + 4)

x/2 = y + 4 (divide by 2)

x/2 - 4 = y (subtract 4)

So, the inverse is y = x/2 - 4

Vitek1552 [10]

The norm of a vector $\vec x$ is equal to the square root of the inner product of $\vec x$ with itself.

a. $\|(-1,2)\|=\sqrt{\langle(-1,2),(-1,2)\rangle}=\sqrt{4(-1)^2+9(2)^2}=\sqrt{40}=2\sqrt{10}$

b. $\|(3,2)\|=\sqrt{\langle(3,2),(3,2)\rangle}=\sqrt{4(3)^2+9(2)^2}=\sqrt{72}=6\sqrt2$
