If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w.r) (x)?

Answers

Answer 1
Answer:

For this case we have by definition that:

(f * g) (x) = f (x) * g (x)

In this case we must find (w* r) (x), so:

(w * r) (x) = w (x) * r (x) = (x-2) (2-x ^ 2) =

We must apply distributive property that states that:

(a + b) (c + d) = ac + ad + bc + bd

So:

(x-2) (2-x ^ 2) = 2x-x ^ 3-4 + 2x ^ 2 = -x ^ 3 + 2x ^ 2 + 2x-4

The range is the set of all "y" values

 Valid That is to say: (-∞,∞)

Answer:

(-∞,∞)
