Answer 1

reflected over the x-axis, compressed horizontally by a factor of 1/2.

Explanation:

y(x) and f(x) means the same.

y = -(2x) means that y(x) was multiplied by -1, and x was replaced by 2x

• -y(x) reflects y(x) across x-axis

• y(a*x) compresses horizontally y(x) by a factor of 1/a. Here, a is 2, then the factor is 1/2.
