Answer: -4, 4 ...... 3 ....... 4 ...... crosses ..... touches

Explanation:

f(x) = -4(x - 4)(x² - 16)³

0 = -4(x - 4)(x² - 16)³

0 = -4 0 = x - 4 0 = (x² - 16)³

not valid x = 4 0 = [(x - 4)(x + 4)]³

0 = (x - 4)(x + 4)(x - 4)(x + 4)(x - 4)(x + 4)

x = 4, x = -4, x = 4, x = -4, x = 4, x = -4

Zeroes: x = -4 multiplicity of 3 and x = 4 multiplicity of 4

odd multiplicity crosses, even multiplicity touches
