Question

Given v(x)=2, and y=-2x, find v(y)?
1) 4
2) -4
3) 2
4) 8

Answer 1

Given that v(x)=2 is a constant and y=-2x, v(y) is also 2, corresponding to choice 3.

Step-by-step explanation:

The student has asked to find v(y) given that v(x)=2, and y=-2x. To find v(y), we need to substitute the expression for y into v(x) to get v(-2x). Because v(x) is a constant function and v(x)=2 for all x, it means that v(y) will also be 2 for any value of y. Thus, the answer to the question is that v(y)=2, which corresponds to option 3 in the provided choices.
