Question

The functions f(x) and g(x) are described below.

f(x) = 7x + 9

g(x) = 7x - 4

The graph of g(x) is obtained by shifting down the graph of f(x) by _____ units.

Answer 1

13 units

Explanation:

Because the c term (9 for f(x)) represents the y intercept. The y only moves the graph up or down. Since we are trying to get from 9 to -4 move down by 13 units.
