Consider a function q defined by q(x) = x2. Explain why negative valu
are not include in the range of q. (From Unit 4, Lesson 10.)

Step-by-step explanation:

The simple short answer is because all real numbers are to be squared.

If any negative value is put into x^2, the value will become positive. That's because an even number of negatives are positive.

For example y = x * x

Let x = - 3

y = (-3)(-3)

y = 9 because there are an even number of negatives.

Notice that if break x^2 into x * x, you should see more clearly that each x is equal to - 3

Step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
