Question

If you shift the linear parent function, f(x) = x, down 7 units, what is the equation of the new function? A. G(x) = 7x B. G(x) = x + 7 C. G(x) = x – 7 D. G(x) = x

Answer 1

Answer:

The correct answer is C. f(x) = x - 7

Step-by-step explanation:

In order to find this, you simply need to know that vertical shifts can be added on to the end of parent equations as constants. Since this is a downward shift, we use a negative number.
