Question 5 • Precalculus
Consider the function .Which statement explains the continuity of the function at x = –1?
Answer
A
Because f(x) = 4 and f(–1) = 4, it follows that f(x) = f(–1). Therefore, the function is continuous at x = –1.B
Because f(x) = –4 and f(–1) = –4, it follows that f(x)= f(–1). Therefore, the function is continuous at x = –1.C
Because f(x) = 4 and f(–1) = –4, it follows that f(x) ≠ f(–1). Therefore, the function is not continuous at x = –1.D
Because f(x) = –4 and f(–1) = 4, it follows that f(x) ≠ f(–1). Therefore, the function is not continuous at x = –1.
