Which of the following statements is TRUE about the function f(x)=(2x+1)(x−1)^3(x+5)? a
The function has four x-intercepts.
b
The function has a zero at (−1,0)
c
The function rises to the left and falls to the right.
d
The function has a y-intercept at (0,−5).

The function is increasing. (True) it’s a linear function and 1/3>0.

The function is decreasing. (False)

The x-intercept is (1,0). (False) If we replace x by 1 we get 1/3 not 0

The y-intercept is (0, 1). (False)

The range of the function is all real numbers. (​True)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
