Question

if u(x) = 2x^2 and v(x) = 1/x, what is the range of U(V(X))?
A. (1/3 , 0)
B. (3, infinity)
C. (-infinity,3)
D.(-infinity, infinity)

Answer 1

did you find \((U(V(x))\)?

Answer 2

I forgot to add +3 for the U(x)..

Answer 3

I believe it's 4+3x

Answer 4

@satellite73 can you help?

Answer 5

Use desmos to graph the three functions. The nice thing about desmos is that we can use function composition. Notice how the last line has `w(x) = u(v(x))`
