Question

4. Marcus uses software to graph f(x) = 3x + 2. Then he changes the function to

f(x) = 3x - 2 and uses the software to graph the new function. Which of the
following attributes of the function changes?
F. domain
G. y-intercept
J. asymptote
H. range

Answer 1

G. y-intercept

Explanation:

Both of Marcus's functions are lines in slope-intercept form:

y = mx +b

where b is the y-intercept.

In his first function, b=2; in his second, b=-2. The value of the y-intercept is what changed.
