Question

I know that it will be of the form `2C(x)=C(x/2)`, but I am still stuck to write the transformed function. Can anybody help?

Answer 1

Substitute and solve.

Explanation:

`C(x) = 190sqrt(x) + 1200`.
You are correct. The operative sentence translates to
`CNEW(x/2) = 2C(x)` -- for all x.

Replacing x by 2x, we have:

`CNEW(x) = 2C(2x)` -- for all x.

Now you can use the function C, replacing x by 2x, to find a formula for CNEW.

`CNEW(x) = 2(190sqrt(2x) + 1200)`
etc.
