Answer:
The answer is c)
Step-by-step explanation:
g(x)=x^2-4
Let

be the

matrix whose columns are

, and let

be the vector whose components are the constants

. Now consider the matrix equation

Multiplying both sides by

, we have

More explicitly, we're writing

Multiply both sides by

and the left hand side can be written as

We're told that

whenever

, so we're left with

Each of

are nonzero, which means their norms are nonzero, which necessarily implies that

, and so the vectors

must necessarily be linearly independent.
The function for the amount saved if they purchase a used drone rather than a new drone from Jim's store is f(x) = 0.45x
He sells used drones at 70% of the price (x).
So, the selling price of a used drone is:

Express percentage as decimal


Also, he sells new drones at 15% more of the price (x).
So, the selling price of a new drone is:

Express percentage as decimal



The amount saved is the difference between the prices of the drones.
So, we have:

This gives

Subtract

Express as a function

Hence, the function for the amount saved is f(x) = 0.45x
