Question 1

Which of the following accurately lists all discontinuities of the function below?

Revolt · Accepted Answer

point discontinuity at x = 4; jump discontinuity at x = –2

Question 2

The graphs of three functions are shown.

Revolt · Accepted Answer

The absolute value and square root function share an x-intercept.

Question 3

The equation of the piecewise function f(x) is below. What is the value of f(–2)?

Revolt · Accepted Answer

f(–2) = 3

Question 4

Consider the functions.f(x) = (x + 1)2 – 4g(x) = –4 |x + 1|

Revolt · Accepted Answer

Since the range of f(x) is limited to y ≥ –4 and the range of g(x) is limited to y ≤ 0, the ranges overlap for the values –4 ≤ y ≤ 0.

Question 5

Which statements can be used to accurately compare the functions? Select two options.

Revolt · Accepted Answer

f(x) has the greatest maximum.; All three functions have a y-intercept.
